Nachiketas knew the secret
Death is the saddest thing in the World. A sudden departure of the known people makes even the Mahatmas cry. Nachiketas meets Lord Yama, the God of death and wants to know the Supreme secret, which is death itself.
One of the best Upanishad is that of Nachiketas. I understand while I read it, but forget it in a day or two. Similarly the death of near one, remains in my mind for a few years or more. But the moment, I eat and begin to think of other people around me, I feel I tend to forget the miserable.
I happened to witness two deaths in this year. One that of a young man whose marriage was fixed, a very hard and knowledgeable worker in a Clinic. He died in a road accident and that was huge shock. Another one was yesterday, that of a very nice Doctor also young. I cried, but still unable to recover from the shock.
