The Yagya-Anusthan refers to Vedic rituals, which are performed as per the procedure scripted in the Vedas. They are performed with or without any intentions. Yajurveda is all about Yagyas. In the old era, Yagyas were a part of daily-life of sages and devotees. Big Yagyas were performed occasionally by virtually everyone.These rituals included Hawan(Fire Sacrifice), and Japa(Recitals of a particular quantity (like 125000 times) of a Particular mantra, which is either from Veda or from a scripture derived from Veda). These Vedic Mantras are perfect in rhythm and therefore very effective in generating fast positive energies. These fast energies can help the person to get healed or get helped by nature. A Yagya contains a donation, which goes to the Pundits, Puja (worship), Prayers, and the Brahmanbhoj (Letting Pundits and cows eat).
