Ego (ahamkara) makes three identifications (tadatmyam): with the reflection of consciousness (cicchaya), with the body (deha), and with the witness (saksi). The first is natural, the second is karmic, and the third one is made out of ignorance.
1. Sahajam tadatmyam: the ciccaya (reflection of consciousness) in the suksma sarira (subtle body) gives rise to the ahamkara. It’s only natural this ego identifies with that consciousness and that consciousness identifies with ego. The resultant experience is “I know.”
2. Karmajam tadatmyam: identification with the body-mind is karmic. For countless reasons, there’s a reflection of consciousness in the subtle body contained within this body-mind. These first two identifications are the work of maya and maya is above our pay grade. In maya but not of maya.
3. Bhranti-janyam tadatmyam: ego is finite but the witness is infinite. The mutual superimposition of ego and witness is one of ignorance and the root of all samsaric suffering. The resultant experience of this misidentification is “I am.” Although avidya is beginningless, it’s not endless. That’s what viveka and nisarga yoga are for.
