Acharya Prashant explains the distinction between 'Shabd Brahman' and 'Parabrahman' based on the 17th verse of the Amritabindu Upanishad. He defines Shabd Brahman as the reality of this world, encompassing everything that can be expressed through words, waves, time, and space. This includes the entire physical universe and the three states of consciousness: waking, dreaming, and deep sleep, symbolized by the sounds 'A', 'U', and 'M' in Om. He emphasizes that a seeker must understand the world through science and psychology to avoid being deceived by superstition or ignorance. Knowing the world is essential, but stopping there leads to a state of being trapped in a 'house' that lacks what the soul truly desires. Parabrahman is described as the reality beyond the world, represented by the silence that follows the chanting of Om. It is the 'beyond' that transcends the three states of consciousness. Acharya Prashant warns against two common mistakes: being spiritual while ignoring worldly knowledge, which leads to blind faith, and being worldly-wise while ignoring the transcendental, which leads to a lack of peace despite vast knowledge. He concludes that a true seeker needs both: a thorough understanding of the world (Shabd Brahman) and a deep thirst for the ultimate truth (Parabrahman). One must keep an eye on the 'beyond' while maintaining full awareness of the 'here and now'.
