Hi young wise friend, what a collection of great answers! I am also impelled to sing my (crow's) tune in this assembly of koyals! Give me an ear for the simple, short note that I would try for you:
Friend, can you yoke a stud bull to a cart or plough? Can it do that work? Can a wild adult zebra be trained in athletics? Don't they catch even animals young, to have them do special activity?
we had a perfect system of education - in the absolute sense of 'change of behaviour' that is, change / addition of knowledge, refined attitude and right actions - whereby young ones were made fit to play their future roles as householders, citizens, profesionals etc perfectly. We do not have them any more.
Can you give a child a sharp knife without telling it how to handle it carefully? Knowledge is like fire and knife, capable of doing great tasks IF and WHEN employed rightly. Else it could hurt the one possessing it. But we do precisely this mistake of providing a secular knowledge with a view to gaining a job, for earning a living, without the lessons to lead the life rightly and training in the art of right thought and actions.
We are half made of nature (Genetics / Karmic endowments) and half of Nurture (environmental grooming). The parents and peers in school and neighbourhood can even improve our nature (or degrade it as well). I remember a story I read as a student:
There was a renowned multilinguist, language scholar who knew several languages, in the court of a king. He spoke each language with such right accent as the people of that language would speak, that no one could find what was his actual mother tongue. The king ordered a prize for one who found his mother tongue. Tenali Raman or someone I think, went to the Pandit's house when he was taking a nap and pricked his toe suddenly, wherefore the Pandit woke up shouting "Evarudaadhi?" in Telugu. He accepted before the king that his mother tongue was telugu. That is it. Our innermost endowments escape from us at the weakest moment.
We are basically animals with a divine possibility - under proper training. If we remain untrained, we would betray our animal quality at the weakest moment. Yogis have to be very careful till they achieve 'samadhi' since our animal mind would ever be wallowing in sensuous thoughts only. Once the joy of 'samadhi' is enjoyed, the mind would not crave for any lesser pleasure like the sensuous stink. After taking a glass of orange juice, would you crave for a peice of orange pulp?
It is easy to understand the problem, since we have had abundant great teachers like Sri Ramakrishna, Ramana, Aurobindo, Sankaracharyas, Sai Babas etc. But we have to remember that still we are standing on the volcano of senses that could blow us up any time.
We have to be ever vigilant. Did not Sri Krishna mention of "sathatham yoginaha" the full time yogis? For, the least carelessness could spell doom for the yogi himself.
If you have caught the tiger by its tail, don't leave it till you reach a vantage point to release yourself safely! Delusion is as powerful as the Divine himself!!
