Acharya Prashant explains that human existence and words are typically ephemeral, like bubbles that appear meaningful for a moment before disappearing. He clarifies that words become everlasting only when they are dedicated to the truth rather than to the self. When actions, thoughts, and words are dedicated to the eternal, they transcend time and become indestructible, similar to the Upanishads, the Bhagavad Gita, or the verses of Kabir Saheb and Rumi. He emphasizes that most people live hollow lives because their actions are self-centered and rooted in time, leading to a chaotic and insubstantial past that they fearfully carry into the future.
