Commentary

Okay, so Krishna is *super* hyping up this Brahman knowledge, tryna get spiritual peeps hyped to achieve it ASAP. It's not some blind faith BS; this royal science lets you *directly* experience the truth – the ultimate secret (aka the Self or Absolute). It's the GOAT of all sciences, the most epic secret ever, and the ultimate purifier. Brahman knowledge is the best cleanser ever; it wipes out ALL your past life karma – like, poof! – in a sec. It destroys ignorance and its effects. Regular atonement only fixes some sins, leaving subtle bad vibes that haunt you in your next life. But this knowledge? It obliterates *everything*, gross and subtle, from thousands of lifetimes. That's why it's the supreme purifier. MulaAvidya is the root of ignorance, and Sthula Avidya is the surface-level ignorance. This Self-knowledge isn't anti-Dharma; it's the reward for all your good deeds across lifetimes. Plus, it's super easy to get. Don't think it's weak because it's easy; it's *imperishable*, forever shining. Once you taste this nectar, you're immortal. So, yeah, you *gotta* hustle to get it in this life, 'cause human life is rare, and the prize (moksha) is huge. Go get it!
