Yajna ( Sanskrit: यज्ञ, romanized : yajña, lit. 'sacrifice, devotion, worship, offering') refers in Hinduism to any ritual done in front of a sacred fire, often with mantras. [1] Yajna has been a Vedic tradition, described in a layer of Vedic literature called Brahmanas, as well as Yajurveda. [2] The tradition has evolved from offering.
