In that we will sit in a quiet state. If we observe we fall in thinking then there is a mantra to bring forth to previous quiet state.
We will be in full awareness but as a dead man. We may hear some sound but we will not go after the sound effortlessly.
is it so. Please guide.
Thanks
The link to the Bihar school and its shoonya meditation is very good. But so unknown as they think is this type of meditation not. I had it lastly while while researching the lines of yogananda and the built up channel and tube behind the spine what Yogani presumably means that from the Kundalini nerve further forms are created in spinal breathing pranayama.
Such astral illusions get broken by losing the separateness of the own body becoming himself empty and an illusion like in a further step their meditation avoids by treating in- and outside still valid.
Also the breaking of the mantra is not shown but they return to it using the om with important differences like in AYP for getting silence.
Dead man is also a good characterisation for the intention of this meditation going further on from pratyahara and dharani to dhyana and its forms like samadhi in the dead corpse pose of sawasana not adviced in AYP.
Before doing a meditation it is always the question if it is fitting for you. It seems that you are a little bit hesitant. It breaks in many ways with our normal world view.
