Vedic culture is the earliest culture of this world. It is based on the fundamentals of Vedas. Yajna (a ritual also known as hawan or Homa, which usually involves offerings to the holy fire) is the heart of Vedic Dharma (Vedic code of conduct). The tradition of the Yajna has been in existence since time immemorial. It was mandatory to perform this ritual in the ashrams of the sages daily (both during morning and evening). We know this ritual by the name of dainik agnihotra. The Yajna is a special process where The yajman or performer, along with his wife offers ahuti into the receptacle in ignited fire after recitation of each Vedic Mantra. The yajna is performed in the presence of various members and priests like Ritwik, Purodha, Acharya, Hota and so on. In ancient time yajna were performed by the kings and emperors under the guidance and surveillance of Rishis, Maharshis and Acharyas (great sages and masters).
