Agnihotra refers to the twice-daily heated milk offering made by those in the Śrautatradition. This tradition dates back to the Vedic age; the Brahmans perform the Agnihotra ritual chanting the verses from the Rigveda. The tradition is now practiced in many parts of South Asia in the Indian sub-continent, including primarily India and most particularly in Nepal. The Brahman who performs Agnihotra ritual is called Agnihotri. The history of Agnihotra ritual — the casting of ghee into the fire, at every sunset and at every sunrise — has been traced from a common Indo-Iranian fire-worship ritual including ZoroastrianYasna Haptaŋhāiti ritual mentioned in the Old Avestan. This was already popular in India with Upaniṣads as religious performance.
Agnihotra rituals in Nepal
Witzel locates the first Agnishala hypothetically at Jhul, in the western ridge of the Kathmandu valley and later at the southern rim of the palace of Aṃśuvermā at Hadigaon, Kathmandu. The first source of inscription evidence was from Tachapal tole, east part of Bhaktapurcity, also shown by a legend that the Maithila King Harisiṃhadeva would establish the yantra of Taleju Bhavānī in the house of an Agnihotri. From 1600 CE onward, the Agnihotra has been attested to the Agnishala temple in Patan only. The Agnihotra ritual in Nepal has been first recorded in an inscription of King Anandadeva in c. 1140 AD that mentions of the initiations of his two sons, viz. Yasho Malla and prince Somesvara at Agnimatha. The temple of Agnishala since the 12thcentury maintains the Vedic tradition of Agnihotra fire sacrifice ritual and despite having undergone many ritual changes, the basic Vedic performance is still intact. The Agnishala is maintained by the NewarRajopadhyayaBrahmins of Patan, who are the premier Krishna Yajurvedic Brahmins of Nepal. Along with these, there are other Agnishalasidentified and recently revived, viz.
at southern edge of Pashupatinath temple by a Purbe Brahmin. This has been in practice for almost 200 years now, and for this Agnishala, in 1974 the government provided NRs. 18,000 per year.
