Acharya Prashant explains that the realization of everything rising and falling to merge into a vast consciousness is often lost because the mind fails to see things as they truly are. He asserts that things do not exist as permanent entities but are merely processes or flows, similar to waves with crests and troughs. To maintain this realization, one must possess a courageous mind that continuously observes the appearance and disappearance of all things, rather than succumbing to the attachment that makes the world appear as a solid truth. He emphasizes that the senses are not subtle enough to capture this moment-to-moment change, leading to a false belief in permanence. He further clarifies that impermanence is synonymous with non-existence; when one recognizes that nothing has lasting existence, only the truth remains. This practice requires immense attention, stamina, and the courage to resist the security and comfort found in the illusion of permanence. Acharya Prashant advises being courageous even in moments of impending pleasure, as such pleasures often depend on being oblivious to the truth. By making truth paramount, one accesses a higher pleasure that surpasses ordinary, worldly gratifications.
