So all sentient beings in the thirty-one planes of existence possess this same sort of mind, with varying particularities in terms of what can be discerned, directed towards, etc. This means that there need be no biological foundation (a nervous system, neuronal configurations, etc) for the mind to exist. Also, if the arising of ignorance presupposes the existence of this mind, then it seems to be outside or independent from dependent origination. Is this right?
Just keep breathing in and out like this. Don't be interested in anything else. It doesn't matter even if someone is standing on their head with their ass in the air. Don't pay it any attention. Just stay with the in-breath and the out-breath. Concentrate your awareness on the breath. Just keep doing it. http://www.ajahnchah.org/book/Just_Do_It_1_2.php
