Acharya Prashant explains the concept of the sacrificial fire, distinguishing it from ordinary fire used for daily chores. This special fire is one that cleanses and is an agent of upliftment. It is the fire in which you offer the best that you can, for the best that you can. It is the means that takes you upwards. The speaker then discusses a prayer to this fire, asking it to lead one towards true prosperity (Aishwarya). He clarifies that the English word 'prosperity' is not an apt translation. 'Aishwarya' comes from the same root as 'Ishwar' (the all-commanding one), so the prayer is for the fire to take one towards God. The practical meaning of this is a complete submission to the fire for purification. One must offer oneself to be purified without knowing the outcome, which is a statement of strong faith and dissatisfaction with the current self. This act of leaping into the flame means being prepared to let the burnable parts of oneself be annihilated. The speaker emphasizes that there is no middle way; one cannot retain their faults and the current self while reaching a higher dimension of being. Liberation is not a positive state but rather freedom from who you are. The question of what remains after liberation becomes irrelevant to the one who is liberated. To approach the flames, one must have contempt for the result and be indifferent, a teaching he links to Shri Krishna. The speaker explains that scriptures like the Upanishads act as 'circuit breakers' for the mind's self-contained and self-ratifying world. The mind's beliefs are constantly reinforced by its own world. The Upanishads introduce contradictions, like stating 'this is full, and that is full,' which the mind cannot logically process. This jolt disrupts the mind's usual functioning, bringing it to a state of silence and peace (Shanti), which is the ultimate mission.
