Acharya Prashant explains that while the ultimate truth or the self is one, the expressions of various gurus differ because they are individuals shaped by their specific time, language, and circumstances. A speaker's personality serves as the medium for expression; for instance, Kabir Saheb spoke in the language of his time and surroundings, not in Sanskrit or foreign languages. Furthermore, the nature of the teaching depends heavily on the listener. Shri Krishna spoke differently to Arjun before the war than he did after the war, and his tone with the Gopis was different still. The level of the seeker's readiness, such as the difference between Arjun's questioning and King Janak's receptivity in the Ashtavakra Gita, dictates the effort and style of the teacher. He emphasizes the importance of 'Vivek' or discernment—the ability to distinguish between the eternal (Nitya) and the transient (Anitya). Many instructions in scriptures are 'time-dependent' or 'situation-dependent' and may become irrelevant as eras change. Acharya Prashant warns against clinging to these literal, situational instructions, such as specific social rules or incidental remarks, while ignoring the core, eternal message. He uses the analogy of a sieve (Sup) that retains the grain and lets the chaff fly away. One must approach scriptures like the Bhagavad Gita only when in the right state of mind, characterized by both doubt and deep respect, similar to Arjun's disposition. Ultimately, he advises listeners not to struggle to memorize words, as the mind often clings to the trivial; instead, one should listen with full attention, allowing the essential truth to settle in the heart naturally.
