UNKNOWABLE is a philosophical inquiry into the limits of knowledge, identity, and certainty, grounded in the Upanishadic method of Neti Neti—neither this, nor that. The book examines what remains when body, thought, belief, memory, ego, and social conditioning are systematically negated. Engaging non-dual philosophy alongside modern science, psychology, and political thought, the work explores the nature of the Self, ego, illusion (Māyā), time, action, and responsibility. Classical texts such as the Upanishads and the Bhagavad Gita are approached as psychological and existential inquiries rather than theological doctrines. Extending beyond the individual, the book reflects on society, religion, and nationhood, arguing that spiritual clarity and collective responsibility are inseparable. UNKNOWABLE offers no doctrines or assurances—only an invitation to observe without belief and to inquire without accumulation.
