Kena UpanishadThe Kena Upanishad is a principal Upanishad that investigates the ultimate source behind mind, speech, sight, and life itself. It asks by whom the mind thinks and the senses function, and points beyond all mental and sensory activity to the reality that makes them possible. The text is treasured for its subtle spiritual insight and its teaching that Brahman is known not as an object, but as the very ground of awareness.Book link ↗
