Can you explain the metaphor of the 'knowledge-sacrifice' or Jnana-yajna as detailed in the source?

The knowledge-sacrifice, or Jnana-yajna, is described in Chapter 50 as a profound internal practice. In this sacrifice, the affirmation "I am Brahman" is the sacrificial post. The five great elements form the canopy, and the perceived difference between the soul and God is the sacrificial animal. The five senses and five life-breaths (pranas) are the materials, while the mind and intellect are the sacrificial pits where the fire of knowledge is kindled. The individual soul (Jiva) acts as the sacrificer, offering the ghee of ignorance as an oblation. This act burns the illusion of separation, manifesting non-dual knowledge and leading to a state of self-bliss.
