Question: In advanced states of meditation does the mind leave the body? People sometimes talk of astral travelling.

Babaji:

These things are really not important. One will lose consciousness of the body and become aware of the Existence of the Supreme Self. One may have experiences of travelling but ultimately they are found to be hallucinations.

The soul is not a piece of something here and there. It is all-pervading. Like with an earthen pot - for some time it appears that the space is in the pot - but 'Space' is everywhere.  We start with this imagination of being in this body. Then with meditation we lose the consciousness of being in the body or out.
