Can you explain the metaphor of the 'knowledge-sacrifice' or 'Jnana-yajna' as it's described in the source material?

The 'Jnana-yajna' or knowledge-sacrifice is a profound metaphor detailed in Chapter 50 for achieving non-dual awareness. In this symbolic ritual, the declaration 'I am Brahman' serves as the sacrificial post. The five great elements are the canopy, and the perceived difference between the individual soul and God is the animal to be sacrificed. The text explains that the Jiva, or individual soul, is the sacrificer who kindles the fire of knowledge in the sacrificial pits of the mind and intellect. The most crucial part is offering the 'ghee of ignorance' as the oblation. By burning this ignorance, the fire of knowledge consumes the illusion of separation, leading to the experience of non-dual reality and a 'ceremonial bath' in self-bliss.
