Day 4:49 am
Going deeper, the mind (manomaya kosa) and its functions are not ‘I’.
The next step takes on to the question. “Wherefrom do these thoughts arise?” The thoughts are spontaneous, superficial or analytical. They operate in intellect. Then, who is aware of them? The existence of thoughts, their clear conceptions and their operations become evident to the individual. The analysis leads to the conclusion that the individuality of the person is operative as the perceiver of the existence of thoughts and of their sequence. This individuality is the ego, or as people say ‘I’. Vijnanamaya kosa (intellect) is only the sheath of ‘I’ and not the ‘I’ itself.
Enquiring further the questions arise, “Who is this ‘I’? Wherefrom does it come?” ‘I’ was not aware in sleep. Simultaneously with its rise sleep changes to dream or wakefulness. But I am not concerned with dream just now. Who am I now, in the wakeful state? If I originated from sleep, then the ‘I’ was covered up with ignorance. Such an ignorant ‘I’ cannot be what the scriptures say or the wise ones affirm. ‘I’ am beyond even ‘Sleep’; ‘I’ must be now and here and what I was all along in sleep and dreams also, without the qualities of such states. ‘I’ must therefore be the unqualified substratum underlying these three states (anandamaya kosa transcended).
‘I’ is, in brief, beyond the five sheaths. Next, the residuum left over after discarding all that is not-self is the Self, Sat-Chit-Anand
