Yadnyakarma, or Yajna (Yagna), is an ancient and profound Hindu ritual of offerings made into a consecrated fire, accompanied by the chanting of Vedic Mantras. The practice is rooted in Vedic times and is derived from the Sanskrit verb ‘yaj,’ which holds a three-fold meaning: worship of deities (Devpuja), unity (Sangathikaran), and charity (Daan). The essential element is the ritual fire, or divine Agni, into which oblations are poured. It’s spiritually believed that whatever is offered into the fire reaches the God. The ritual involves sublimating havana samagri (herbal preparations), along with large quantities of ghee, milk, grains, and samidha. Priests play crucial roles by reciting invocations from the Rigveda and offering three kinds of oblations (those that blaze up, those that make noise, and those that sink). The duration varies, lasting hours, days, or even years, and can be private or public. Major types of Yajnas, such as Ganesh Yagna, Mahamrityunjay Yagna, and Sudarshan Yagna, are performed for various reasons, including long life, flourishing business, and overcoming health problems.
