Can you elaborate on the concept of the 'knowledge-sacrifice' (Jnana-yajna) as a method for burning away ignorance?

The 'knowledge-sacrifice' or Jnana-yajna is a profound metaphor for the internal process of realizing non-duality. As detailed in Chapter 50, the declaration 'I am Brahman' serves as the sacrificial post. The five great elements form the canopy, while the perceived difference between the individual soul (Jiva) and God is the sacrificial animal. The individual soul, as the sacrificer, uses the fire of knowledge kindled in the pits of the mind and intellect to offer the 'ghee of ignorance' as an oblation. By burning away the illusion of separation, this sacrifice manifests non-dual knowledge and allows the soul to be immersed in self-bliss.
