Acharya Prashant explains that the human mind tends to perceive existence in a divided way, primarily through the distinction between the self and the universe. This separation is represented by the concepts of Vidya and Avidya. Avidya refers to the knowledge of the external universe gained through sensual perception, while Vidya refers to the knowledge of the self. He argues that the Rishis taught that these two must be known together because they are mirror images of each other; the outer world is merely a representation of the inner mind. To see them together is to stand as a witness, separate from the duality of subject and object. He further elaborates that freedom from death is achieved through Avidya, while immortality is attained through Vidya. By fully knowing the nature of the universe, one realizes its falseness, which in turn dissolves the fear of death, as a false universe can only produce a false death. Immortality, however, goes beyond the mere absence of death; it is a state of total freedom from both the concept of death and the concept of 'no-death.' This state is reached when both Vidya and Avidya are dissolved, allowing only the Truth or Brahman to remain. Acharya Prashant emphasizes that spiritual seekers must eventually drop both material and spiritual knowledge to reach this ultimate state. Addressing the practical application of these concepts, he critiques the habit of naming and categorization, which he suggests makes life repetitive and uncreative. He notes that people often listen to spiritual truths without letting them disturb their established patterns of living. He asserts that the ego is the false distinction that creates the apparition of 'internal' and 'external' from nothing. True seeking requires a one-pointed inquiry and the sincerity to live according to one's realizations, rather than merely collecting intellectual knowledge while remaining attached to old habits and worldly identities.
