Acharya Prashant discusses the concluding verses of the second chapter of the Shrimad Bhagavad Gita, known as Sankhya Yoga. He explains that the chapter begins with the teaching of self-knowledge (Atma-gyan). The ego (ahankar), which arises from physical tendencies and social influences, is what common people, including Arjun, mistake for their true Self (Atma). The fundamental error begins with the thought of 'I' (Aham). What we call 'I' is not the real 'I'; the real 'I' is unknown. The entire purpose of self-knowledge is to stop identifying with that which you are not. The teaching of self-knowledge, while pure and simple, is difficult for those filled with attachment (moha) and who have lived their lives based on beliefs and notions. To them, self-knowledge feels like a painful loss of everything they possess and are. The false 'I' has a name, a body, knowledge, wealth, a past, and memories. Self-knowledge doesn't just take away what you have; it takes away the 'you' who has it. This feels like death. For those not ready for this direct teaching, Shri Krishna offers the path of Nishkama Karma Yoga (action without desire). Acharya Prashant quotes the verse, "The man who, giving up all desires, moves about without longing, without the sense of 'I' and 'mine,' he attains to peace." He explains the terms 'nirmam' (without 'mine'), 'nirahankar' (without 'I'), 'nispriha' (without longing), and 'vigat kaam' (one who has gone beyond desires). He states that egoism (ahanta) and the sense of 'mine' (mamata) are inseparable. The extent of one's ego is revealed by their attachment to 'my' things. He criticizes the foolish logic of needing to make more mistakes to learn, asserting that a wise person learns from a few mistakes or even by observing others. The one who doesn't want to learn will repeat the same fundamental mistake in countless forms, believing each situation is new. He concludes by differentiating spirituality from conventional morality and culture, which are often products of the ego. Spirituality, as taught by Shri Krishna, aims to dismantle this very ego.
