Who am I by Bhagwan Ramana Maharishi
'Who am I?' The
physical body, composed of the seven dhatus, is not 'I'. The five sense
organs… and the five types of perception known through the senses… are not 'I'.
The five parts of the body which act… and their functions… are not 'I'. The
five vital airs such as prana, which perform the five vital functions
such as respiration, are not 'I'. Even the mind that thinks is not 'I'. In the
state of deep sleep vishaya vasanas remain. Devoid of sensory
knowledge and activity, even this [state] is not 'I'. After negating all of the
above as 'not I, not I', the knowledge that alone remains is itself 'I'. The
nature of knowledge is sat-chit-ananda
[being-consciousness-bliss].
