When you are sad or in pain or sick or you witness any cremation then you actually learn the many truths of life.
When a man has reached the point where he can sit in meditation for six months, there is no need of eating, no need of latrine or of rest. Only one drop of amrit nectar from the top of the head to the body keeps him alive. If a tiger eats that body there is no care, but only when the life comes back to the body will there be pain.
If you are free of attachment, you will lead a simple life in a simple environment.
