Acharya Prashant explains that spiritual concepts like the five elements, the sheaths of the soul, and the states of consciousness are not complex models but become clear as one understands life. He advises against approaching these topics through bookish knowledge, as it often becomes a mental burden rather than a practical tool. Instead, he suggests staying close to life and the processes one is currently undergoing. He describes the scriptures as simple, almost childlike, but notes that they appear complicated due to the different historical contexts and the interpretations of commentators. He simplifies the states of consciousness by categorizing the waking, dreaming, and deep sleep states as the first level, characterized by varying degrees of restlessness, while the fourth state, Turiya, is the second level of peace and silence.
