The Mandukya Upanishad describes Turiya as following:- “Turiya is not which is conscious of the inner (subjective world), nor that which is conscious of (objective) world, nor that which is conscious of both, not that which is mass of consciousness. It is unperceived (by any sense organs), incomprehensible (to the mind), unrelated (to any object), uninferrable , unthinkable, and indescribable. It is essentially of the nature of consciousness , constituting the self alone, and is the negation of all phenomena; it is the peace, bliss and One without a second. It is known as Turiya. It is Atman, and it is to be realised.
