Can you explain the concept of the 'knowledge-sacrifice' or 'Jnana-yajna' as a way to burn away ignorance?

The knowledge-sacrifice, or Jnana-yajna, is a profound metaphor for achieving non-dual knowledge. As detailed in Chapter 50, this sacrifice involves seeing Krishna, or God, in every being and place. In this ritual, the declaration 'I am Brahman' serves as the sacrificial post. The five great elements form the canopy, while the five senses and five pranas are the sacrificial materials. The Jiva, or individual soul, acts as the sacrificer. From the sacrificial pits of the mind and intellect, the fire of knowledge is kindled. The Jiva then offers the oblation of the 'ghee of ignorance' into this fire, burning away the perceived difference between the soul and God to manifest non-dual knowledge.
