A Chinese parasol tree against a high rise,
I wouldn't dare compare;
God's creation and that of man has no price,
with nothing common to pair. 

The tree has no stairs or lift to take me up,
yet it arms embrace me high
into the sky beyond my sight and cross the gap
between earth and the blue sky.

The building is but a shell, an empty dead shell, 
transient its inhabitants are;
like hermit crabs on the run and returning, tell
of the weather if bad or fair. 


And the parasol tree stands witness to man's
incessant and endless toil;
telling him of the seasons passing in the sands
of time, sans regret, recoil.    









Chinese parasol Cavanillesia hylogeiton Malvaceae, UST Manila  
Cavanillesia belongs to the same family as the baobab Adansonia. 





Baobab is also called 'boab', 'boaboa', 'bottle tree', 'the tree of life', 'upside-down tree', and 'monkey bread tree'. It grows in Madagascar, mainland Africa, and Australia. The baobab is the national tree of Madagascar. "The Big Baobab Pub" South Africa is 22 metres (72 ft) high, 47 m (155 ft) in circumference, and is said to have been carbon dated at over 6,000 years old
The baobab tree is known as the tree of life, with good reason. It can provide shelter, clothing, food, and water for the animal and human inhabitants of the African savannah regions. The cork-like bark and huge stem are fire resistant and are used for making cloth and rope. The leaves are used as condiments and medicines. The fruit, called "monkey bread", is edible, and full of vitamins.

The fruit has a velvety shell and is about the size of a coconut, weighing about 1.44 kilograms (3.2 lb). It has a somewhat acidic flavor, described as 'somewhere between grapefruit, pear, and vanilla'. The tree can store hundreds of liters of water, which is an adaptation to the harsh drought conditions of its environment. The tree may be tapped in dry periods. Mature trees are usually hollow, providing living space for many animals and humans. Trees are even used as bars, barns, wine and beer shops and more.~

Great Awakening

I woke up on the wrong side of bed one sunrise
And opened the wrong door, the backdoor;

Saw my banana plants cut down by my neighbor,
And I, in anger, cut him down in reprise.

This is my life at the other side of midnight,
In a penitentiary for ten years or so
Recreating the life that I failed to do
Behind bars, training afar my sight.

How can I paint life I didn't live up with?
Take it from Van Gogh, or Rembrandt,
Masters of art, yet to the world, servants;
Humble in recluse, fully they had lived.

I want to be remembered, he told me,
Even only by my wife, my little ones I left;
But what heritage awaits a convict bereft
Of freedom, honor and dignity?

Through the bars he saw birds flying high,
Through the bars came the sun and the moon;
Clouds in many faces rolled on and on
And many an angel came passing by.

Give me a brush and paint, a bit of the sun,
He asked, thereupon a new dawn fell on him.
Days and nights grew longer it seemed
Til man, heaven and earth became one.

In his painting people called each other brethren,
Singing hymns of hope and compassion,
Of man striving at each life's station,
On the road to salvation and Heaven.

Organic Farming - More and More People are Going for Natural Food

Virtually no palate can resist bagnet (lechon kawali),
in spite of its high cholesterol content.


Abe V. Rotor

Good health and good food go together, doctors all over the world tell us. Even our children quite often explain to us the importance of proper nutrition, balanced diet, fortification with vitamins and minerals. They tell us to take high protein food, or ask us if we are taking adequate calories. Lately such terms, beta-carotene and good cholesterol have come into the picture.

Now I hear a new term, probiotics. The way I under-stand these substances is that they keep our body always on the alert to fend off stress as a result of overwork and diseases. They are front liners and act as defense shield, Now if probiotics and antibiotics (substances that directly kill germs) work together, can we then say we can have better health and longer life?

Apparently yes, confirmed a balikbayan United Nations official who is working on a new food source from cyanobacterla or blue green algae. Again, this is a revolution in food and agriculture by the fact itself that we are now taking unconventional food such as Spirulina, an ancient organism probably the first kind of living thing that appeared on earth.

Going back to the main topic, I would like to see the other side of the fence. There are many reported ailments and abnormalities, which are traced to the food we take, and it is not only for the lack of intake. Cancer for instance, is often related to food. So with high uric acid which leads to kidney trouble. High blood pressure, high choles¬terol, high sugar level. Aftatoxin causes cirrhosis of the liver. Ulcers are food related. So with many allergies.

Given these premises, I would like to discuss a new frontier of agriculture which I believe4 is also the concern of other sectors of the food industry. It is not only that we must produce enough food. We must be able to produce quality food, which ensures good health, reduces risks to diseases and ailments, and prolongs life. This is the topic that I would like to take up with you in this special occasion, the 25th year or silver anniversary of NFA that I was once a part. I am going to talk about food, which should contribute to good health, long life, enjoyment, and peace of mind.

Here then are seven postulates to address this challenge to present day agriculture. We reckon the Green Revolution in the sixties which ushered production gains from improved varieties and techniques, followed by another wave in the seventies and eighties which was responsible in opening the fields of mariculture (farming the sea), and conversion of wastelands into farmlands. We soon realized that there is need “to go back to basics". Thus ecological farming was born. It is also farming with a moral cause: the enhancement of quality life, good health and long life on one hand, and the maintenance of an ecologically balance environment.

1. IT IS ALWAYS BETTER TO EAT FOOD GROWN UNDER NATURAL CONDITION THAN FOOD GROWN WITH CHEMICALS. This statement can be captured with one term "natural food". All over the world this is a label is found on food grown without chemicals. People are afraid of becoming sick because of the chemicals introduced into food. They know that chemical fertilizers and pesticides go with the crops and are passed on to the body destroying our organs and systems.

2. PEOPLE ARE AVOIDING HARMFUL RESIDUES AND ARTIFICIAL ADDITIVES IN FOOD. A trace of certain farm chemicals is enough to condemn a whole shipment under the rules of the US Food and Drug Administration. One kind of residue that people are avoiding is antibiotics. Poultry and hog farms maintain high antibiotic levels to safeguard the animals from diseases. In so doing the antibiotics is passed on to the consumers. In the first place our body does not need antibiotics. But every time we eat eggs, chicken1 pork chop, steak, and the like, we are taking in cumulatively antibiotics. This makes our immune system idle. This punishes certain organs like the kidney and liver. To others, antibiotics cause allergy.

Another culprit is radiation. Traces of radiation can be hazardous. Many countries immediately took drastic action to avoid contamination following the Chernobyl nuclear plant accident ten years ago. Then we have toxic metals emitted from manufacturing and from vehicles. These are mercury, cadmium, and lead, to name the most common pollutants in our waters today.

Additives such as food colorings and fillers are looked upon with suspicion.

3. PEOPLE ARE BECOMING MORE CONSCIOUS OF THE NUTRITION VALUE OF FOOD RATHER THAN ITS PACKAGING AND PRESENTATION. Many people now reject junk foods, even if their packaging is attractive. Softdrinks have taken the backseat, courtesy of fruit juices and mineral water. People have even learned that plant varieties have different levels of food value even if they belong to the same species. To a lesser extent this is also true among the different breeds of an animal species.

4. FRESHNESS IS THE FIRST CHOICE CRITERION FOR PERISABLE FOOD. Indeed there is no substitute to fresh-ness, a function of handling and marketing. The farmer has the first and direct hand in enhancing this quality. If he keeps his plant; healthy, their products will 'have longer shelf life. Products free from pest and diseases stay fresh longer.

5. FOOD PROCESSING MUST BE APPROPRIATE AND SAFE.
Processing such as drying, milling and manufacturing, is key to higher profit. The profit that is generated from it is referred to as value-added to production. Economists tell us that there is money in postproduction and marketing.

6. FOOD MUST BE FREE FROM PEST AND DISEASES.
It is shocking to find certain pest in food. So with the possibility that food is a carrier of disease organisms. Reports about infested NFA rice needs serious attention. Poor rice is an insult to the Filipino whatever is his economic status.

There has been news of food poisoning too, as a result of food deterioration, or contamination. Remember the Seven Eleven Store mass food poisoning? For a reputable establishment, such an accident deserves something to look deeper. What is the truth behind image building and advertisement?

7. FOOD PRESERVATION MUST ENSURE QUALITY, AND ABOVE ALL, SAFETY. Be aware of the fish that is stiff yet looks fresh. Be keen with formalin odor. Salitre is harmful, so with vetsin. Too much salt is not good to the body. I saw a puto maker use lye or sodium hydroxide to help in the coagulation of the starch. Sampaloc candles are made bright red with shoe dye. So with ube to look life real ube.

Now I am going to discuss in details each postulate as it applies to the farmer, and the condition of his farm. I will try to relate the issue with actual practices so that we can draw up innovations to improve them, as we explore technologies that would settle certain issues.

NATURAL FARMING
The other name of natural farming as we all know is organic farming, that is the use of organic fertilizers instead of chemical fertilizer such as urea and NPK or complete fertilizer. In the US and Europe, people go for organically grown food. Lately in malls and big groceries, we find rice in package or bag labeled "organically grown rice". Let me point out that the use of organic fertilizer must be complemented by other factors.

First, the organic fertilizer must be free from pathogen that causes diseases. Second, it must not carry toxic waste or metal as this kind of fertilizer is manufactured from waste materials.

And third, It must go hand in hand with no spraying, or if it can not be helped, at least the spray used is biodegradable, such as substances that are of botanical derivatives like derris, neem and chrysanthemum.

Reflections on the Ebb of Life

Ruins of Lighthouse and Ship, oil painting (28" x 36") AVR 

You are alone at your lowest ebb.
At low tide the sea reveals her shore
That bathes under the sun to its edge.
Go to the sea and learn its chore.”


- AV Rotor, Nymphaea: Beauty in the Morning, 1996

A man can accomplish anything he sets out to do, but he needs the strength of character propped up by personal values, the seasoning of time, the drive to reach a goal - and the willingness to pay the price of achievement which is not synonymous with happiness, not even with success.

I was then a young teacher when the student demonstrations reached mob level in practically all the big universities and colleges in Metro Manila. That was in the early seventies prior to Martial Law. I decided to quit teaching and return to the farm where I grew up. Materially it was a poor choice, but it was one of the best moments of respite in my life to gather strength and courage. With spontaneous self-evaluation I saw what I wanted in life. It was also a time for self-education, a kind of self-fulfilling acquisition of new knowledge, “a discipline that keeps a man driving toward hard and distant goals,” in the words of James Michener, a great novelist.

Earlier, just after graduation from college, I employed the same strategy. Strategy, you call it, but I would say recourse. For when a man has his back on the wall, either he puts up a bravado stance, or simply gives up. I had taken the latter.

Here, liberated from the heavy demands of city life, I remembered a Chinese philosophy, “When there is no time for quiet, there is no time for the soul to grow. The man who walks through the countryside sees much more than the man who runs.”

Here, I developed many things, which could have been impossible to do in the city, not for lack of space, but for lack of time. I had all the time.

Creativity

The capacity to be creative is inherent in human beings, and the utilization of that capacity is hard work. Michael Drury, a psychologist defines creativity as not only hobbies or taking courses or keeping busy. It is work that goes everywhere. It is a sustained effort toward an ideal.

I tried my hands on oil painting and began developing keener awareness of details of my subjects – the farm and the landscape. Above this, I began to see the meaning of their existence, and the subjective interpretation of form, shape, color, perspective and the like - the very components that the scenery is made of and how in the eyes of the artist relates it to life. Two years later the famous Philippine journalist, Teodoro Valencia, was asking me if I could paint sceneries of his childhood in Batangas. It was a big break for me as a budding painter.

Creativity is not so much as aptitude as an attitude. The exact process is not known, although admittedly it is an immanent beginning in response to things greater than ourselves. Beyond many things, simple as they are, come reflection, an awareness of awareness, taking notice of our thought. Helen Keller wrote, “When we let a resolution or a fine emotion dissipate without results, it means more that lost opportunity; it actually retards the fulfillment of future purposes.”

Self-Education

“Never stop learning,” says James Michener. Just as he learned that the war
(Second World War) had been won by the Allies, he and some officers immersed themselves into fruitful occupation, rather than loafed and let the days pass by. It was when he began writing his famous book, “Tales of the South Pacific.”

It was in isolation that Michener realized the value of self-education. It is also when you are detached that you find a better vantage point.

“I know now that the good work of the world is accomplished principally by people who dedicate themselves unstintingly to the big, distant goal.” He said. Weeks, months, years may pass but the good workman knows that he is gambling on an ultimate achievement which cannot be measured in time spent. Responsible men and women leap to the challenge of jobs that require enormous dedication and years to fulfill, and are happiest when they are involved.

Why is it that some people go back to school many years after receiving their diploma? I appreciate the attitude of these people. To them it is more than just the accumulation of new knowledge. It is the piecing up together of known things into something bigger and whole, the deepening of perception of things around and the awareness of what is ahead. All these are unconscious products of self-education.  I would tend to believe that people enroll in the graduate school to formalize acquired knowledge with experience, amalgamate them structurally, and record them in a book.

As one indulges in self-education, he becomes a “generalist”, moving away from the narrow path of specialization. It appears today that what the world needs more are well-rounded human beings, although specialization is important in developing objective thinking. Self-education puts subjectivity into decisions we make, and into our very actions. It adds the humanity ingredient, the spice of culture, and the magic of aesthetics to the otherwise prosaic and mechanical.

Self-Honesty

Failure in self-honesty is often the root of emotional and mental disturbance. This I learned in psychology. It is no wonder why promising men ruin their careers because they are poor judges of their own abilities and aptitudes.

When I sought contemplation on the farm it was time I felt I no longer liked my career as a teacher. Was I deceived to serve a meaningless cause or was I a victim of self-deception. I wondered if I was “other directed” - looking toward the goals, ideals and ideas of other people for guidance, rather than searching these from within myself. Or, was I looking into the misdoings and misgivings and not on my very own? Have I placed myself on a pedestal of ideals and refuse to confront the real issues down below?

Perhaps I had overdone a work not the calling of the times, or heeded merely the call for work rather than that for service.

Only when one is detached from the maze of human relationships that he knows how to define his role. It is very difficult and it demands a lot of courage to do so. It is like drawing out a single strand from a knotted ball, then sewing this thread into the fabric, now with a definite purpose.

Going back to your feet with determination, strength and precision of what you intend to do is the consequence of self-honesty evaluation. “The person who achieves mature self- knowledge is no longer afraid of life,” says Dr. Carl Rogers. “He recognizes that it rests within himself to choose his way of living.”

It sounds truly Augustinian and Thomasian. Man has the power to choose the way either to the city of man or the city of God.

This is the closest "living" place outside the earth. It has water, in fact an enormous amount 150 km deep and covered by an icy crust as thick as 15 km. From the geysers and cracks, sodium chloride, the common salt of the earth's ocean, has been detected together with other elements and compounds that convince scientists that Europa is a suitable host to life. How heat is generated to maintain its interior a watery mass and perhaps warm, is by the gravitational flexing by its sister moons as they pass, a principle called tidal heating.

Europa has a size approximately like our moon

Europa was discovered on 8 January 1610 by Galileo Galilei, and possibly independently by Simon Marius. It is named after a Phoenician noblewoman in Greek mythology, Europa, who was courted by Zeus and became the queen of Crete.~

Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe: extraterrestrial life and life on Earth. This interdisciplinary field encompasses the search for habitable environments in our Solar System and habitable planets outside our Solar System, the search for evidence of prebiotic chemistry, laboratory and field research into the origins and early evolution of life on Earth, and studies of the potential for life to adapt to challenges on Earth and in outer space. Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does. The term exobiology is similar but more specific — it covers the search for life beyond Earth, and the effects of extraterrestrial environments on living things.(Wikipedia)

Proteomics, a new science to detect human disease

Mapping the human genome helps scientists determine risk factors for disease.  Searching proteins tells us about the state of  a disease in patients now. Since the sequencing of the genome was completed in 2003 scientists have been able to figure out which mutations will make us vulnerable to certain diseases such as cancer, cardiovascular disease, Parkinson's disease, Huntington's disease, Alzheimer's disease, including autism and depression. Computing power has tremendously increased with almost 20,000 genes so far, have provided a DNA map that helps drug companies to target specific mutations. 

But it is not the genes themselves that make us, it is the proteins which they produce which they dispatch into our body to execute genetic will. If the genes are the blueprints, the proteins are the working parts controlling every cell in our body. And just as the genes collectively make up the genome and have given rise to the science of genomics, so too do all our body's proteins make up our proteome, which has its corresponding discipline: proteomics

The field of proteomics that is currently attracting a lot of investments is biomarkers, which can predict with greater accuracy who is susceptible to a particular disease, and help doctors diagnose and treat it earlier and treat it.  The market for biomarker technologies is expected to more than double by 2015 - from $13.5 billion in 2010 to $33 billion in 2015.  (Time, May 20, 2014).~

Sing or play an instrument with eyes closed as you would when praying.  Or listening to Hating Gabi, serenade by Antonio Molina,  Nocturne by Chopin, and Beethoven's Moonlight Sonata on the piano. 

Starry Night painting by Vincent Van Gogh.  A song was composed from this painting - Vincent (Starry, Starry Night

There in the darkness of the mind come alive the melody, the drama, the scenario that are more vivid than when you were under the influence of light, and the ambiance of the surroundings we neither can create nor possess alone. 

Darkness distills our experience during the day - the many scenes that passed before our eyes, sounds that strained into our ears, stimuli our senses capture willingly or not, from the incessant struggle of daily living. 

We surrender to darkness as if it were our refuge, like in the maternal comfort of the womb, or the purity of innocence in Plato's Allegory of the Cave.  We surrender to the voice in darkness that converted Saul into a saint - St Paul the apostle, to the prayerful realm of a blind girl, Fatima Soriano; the classical vision in a blind tenor-songwriter and lawyer, Andrea Bochelli. (photo, left)

Darkness makes the following day beautiful, as day makes a well deserve rest in the night for the body and  spirit to settle down in surrender and peace. Darkness recharges our will and strength, refocuses our direction and goal, restarts our tired mind, calms down our racing heart and pulse.

Didn't the exodus led by Moses happen at night, and wasn't in darkness on Mt Sinai that God handed him the ten commandments?  It was in the dark when God appeared to Abraham and promised him "more descendants than the stars"? Didn't the Resurrection take place in a dark cave?

Gautama Buddha meditated in the caves of northern India.  Mohammad received the Koran in a cave outside Mecca.  St Francis prayed in a tiny grotto near Assisi. Bruce, the Scottish
hero, retreated into a cave to escape his enemies and there watched a spider painstakingly built a web.  Inspired, he rebuilt his army, fought the English king and gained back his throne. 


Famous writers found the dark the best place to express themselves. John Milton (photo, left) wrote Paradise Regained in his blindness, in contrast to Paradise Lost  he wrote while his sight was not yet impaired. Helen Keller, blind since infancy, "saw" in three days in an article she wrote" If I were given three days to see." She saw and experienced the world for so short a time. She saw more than we who can see have seen.  

Author of Let there be Night, and preacher Barbara Brown Taylor recommend these simple ways to appreciate the dark: A walk in the dark can lead to wisdom, deliver us from fear and Taylor believes, bring us closer to God.
1. Walk slowly at night (where it is safe, AVR). 
2. Watch the moonrise.  
3. Unplug all your devices at night, and 
4. Sit in a closet (as close as a cave as city dwellers can get.) 

Author's Note: Fear of the dark is a common fear among children and, to a varying degree, of adults. Fear of the dark is usually not fear of darkness itself, but fear of possible or imagined dangers concealed by darkness.  It is recommended that people who are suffering of nyctophobia or achiuophobia, the phobia of fear should get medical advice before undertaking these steps.~

Force ripening of banana, more so if harvested before full maturity, may lead to bacterial and fungal rot,  usually starting at the peduncle (fruit attachment).  Atis (Anona squamosa) attacked by atis borer, a scrourge of  other members of Family Anonaceae, like guyabano and anonang. Guava attacked by the fruit fly, Dacus dorsalis, which also attacks mango, cucubits (e.g. cucumber, ampalaya), oranges and many other fruits worldwide. These two insect pests are controlled by bagging, that is wrapping the newly formed fruit with paper or plastic but this is laborious.  Growers resort to chemical spraying that provides protective cover to the tree.  Recently systemic insecticides are used.  The active principle is absorbed by the plant and circulated in its sap, rendering its sap poisonous to the feeding insect.  Extreme care should be exercise when using insecticides.

Life and the Traffic Light

Time is likened to the traffic light;

It signals you to go or to stop;

It comes in cycles like in a flight; 
Not a wink, and rest is but a gap - 
Warning nil when your time is up. ~


For Today: Give a new lease of life to your used pencils - and feel happy.

... a little ingenuity, a simple expression of beauty, a little act of goodness -  and a little prayer.

The art of gleaning extends far and wide, and now with pencils (and capless ballpens) thrown away before their time is up - why not give them another chance?

Simply wrap up,roll over each one a colorful, pliant paper from handouts and color magazines (just like the photos show), and there you have made a beautiful piece of art!

Pencil stubs once more fit for writing - oh, how precious they are to you their savior; they have defied the category of waste for the duration of their second life; 

Like scabbards you sheath an unassuming dagger, saving someone from getting stabbed on the skin or in the eye, in a simple act of  "prevention by protection" principle;

Why didn't the manufacturer think of that? To provide safety caps to pencils before they reach the market, to warning of danger school kids, and grownups too? 

There is meaning in small things, we do -  a bit of economy, a little ingenuity, a simple expression of beauty, a little act of goodness -  and a little prayer.~
