Acharya Prashant explains that the ultimate aim of life is peace, which is achieved through a deepening of consciousness. He asserts that consciousness is the only liberator and the only thing worth respecting. This respect for consciousness is the reason why killing a Buddha, a Brahmin, or any human being is considered a grave crime. He argues that if one respects consciousness, one must extend that respect to all beings, including animals and plants, as they also possess consciousness, albeit at different levels. He emphasizes that for one's own liberation and self-interest, one should avoid killing conscious beings, as failing to respect consciousness in others leads to a lack of respect for one's own consciousness.
