Prashna UpanishadThe Prashna Upanishad is composed of six questions (prashnas) put by six earnest seekers to the sage Pippalada. Through their inquiry it explores the origin of beings, the role of prana, the inner light of consciousness, the nature of dreaming and deep sleep, the symbolism of OM, and the supreme Person within the heart. It is a key Upanishad of the Atharva Veda and is widely used in the Vedantic tradition.Book link ↗
