Live on Air Only

May I ask you if it is really a need to live only on prana for the spiritual life ?

Nowadays it is near impossible to live only on air for any length of time because isolation is required if one is to do that. One would have to conserve the psychological energies and be living out of the proximity of others. Otherwise it is not possible.

As for the need of it. That would have to be answered by reviewing the yogi’s motive for doing so on an individual basis. We read that Buddha got to a stage where he lived on air only. His body turned into skin and bones. Also Hiranyakashipu is the yogi who maxed out on this, as he was congratulated by the Brahma deity for excelling everyone in this skill or living only on the life force because he was still alive even though his flesh and bones were long eaten by ants who built an ant nest using his bones as the framing for their nest

But he was a ku-yogi or a criminally motivated one. So that means that one may do this and under it may be ulterior motives.

According to Gautam Buddha his skin and bones austerities did not yield the enlightenment which he was trying to get at the time. So he ceased the practice.

So that is the history of it. You can form your own conclusion.
