Acharya Prashant explains that while the absolute truth is unthinkable and unreachable for the human mind, spiritual practice involves ascending the relative levels of consciousness. Using the metaphor of a four-story house, he describes how a person suffering in a cold, dark basement can use the light of the sun to climb to the top floor. Although the person does not reach the sun itself, which is millions of kilometers away, climbing to the highest possible personal level allows them to receive the sun's warmth and grace. This ascent represents the rejection of falseness and the movement toward higher possibilities within one's own capacity.
