A wise person makes no effort to conceal a secret. But he does not make an effort to reveal a secret either. For example, you do not talk about menstruation, death, etc. to a five-year-old, but as they grow older these things are not hidden from them anymore. They become known as a matter of course.
An unenlightened one tries to protect a secret; and he also reveals the secret at the wrong time, to the wrong person, in the wrong place and makes a big fuss about secrets. Trying to protect a secret causes anxiety and discomfort.
An ignorant one is not comfortable with a secret, whether revealed or un-revealed, but the wise one is comfortable with a secret whether revealed or un- revealed! There are five secrets which are sacred and are guarded by the subtle beings and angels in this creation. They are:
1. Jananarahasya (the secret of birth): Birth is a secret. How a soul takes a body, the criteria for selecting the place of birth, time of birth, type of body, parents, etc are all a secret.
2. Maranarahasya (the secret of death): Death is a highly guarded secret. Death remains a mystery. The process of separation of spirit from matter and its journey from then on is a secret.
3. Rajarahasya (the royal secret, the secret of ruling): The principles of governing; the principles of maintaining the orderliness in creation are a secret.
4. Prakritirahasya (the secret of nature): Nature is a mystery. The more you know about nature, the mystery deepens. The more a scientist knows, the more he feels there is much more to know. Science, though appearing to resolve the mystery in creation, has deepened it. The knowledge of particles, wave functions, black holes, the vacuum state, etc have only deepened the mystery.
5. Mantrarahasya (secret of mantras): The mantras and their effect, influence, method and mode of working are all a mystery. Mantras are the impulses or rhythms of consciousness, which itself is a mystery.
Usually in the West, a secret is shameful and dishonest. But in the East, it is honored and regarded as sacred.
