Yajna has been a part of an individual or social ritual since
Vedic times. When the ritual fire – the divine
Agni, the god of fire and the messenger of gods – was deployed in a Yajna,
mantras were chanted. The
Vedangas, or auxiliary sciences attached to the Vedic literature, define Yajna as follows:
Definition of a Vedic sacrifice Yajña, sacrifice, is an act by which we surrender something for the sake of the gods. Such an act must rest on a sacred authority (
agama), and serve for man's salvation (
shreyortha). The nature of the gift is of less importance. It may be cake (puroḍasha), pulse (
karu), mixed milk (
saṃnayya), an animal (
pashu), the juice of soma-plant (soma), etc; nay, the smallest offerings of butter, flour, and milk may serve for the purpose of a sacrifice. —
Apastamba Yajna Paribhasa-sutras 1.1, Translator: M Dhavamony In the Upanishadic times, or after 500 BCE, states Sikora, the meaning of the term Yajna evolved from "ritual sacrifice" performed around fires by priests, to any "personal attitude and action or knowledge" that required devotion and dedication. The later Vedic Upanishads expand the idea further by suggesting that
Yoga is a form of
Yajna (devotion, sacrifice). It states, "by making one's own body as the lower friction sticks, the syllable
Om as the upper friction sticks, then practicing the friction of meditation, one may see the
Deva who is hidden, as it were". Early Vedic period offerings involved animal sacrifice, but the rituals were progressively reinterpreted over time, substituting the offerings and making it non-violent or symbolic, with the superiority of knowledge and celebration of sound of mantra replacing the physical offerings. Ultimately, the external rituals were reformulated and replaced with "internal oblations performed within the human body". The Vedic text
Satapatha Brahmana defines a sacrifice as an act of abandonment of something one holds of value, such as oblations offered to god and
dakshina (fees, gifts) offered during the yajna. Tadeusz Skorupski states that these sacrifices were a part of ritual way of life, and considered to have inherent efficacy, where doing these sacrifices yielded repayment and results without the priests or gods getting involved. The Buddha sought return to more ancient values, states Tadeusz Skorupski, where the Vedic sages "had study as their grain and wealth, guarded the holy life as their treasure, praised morality, austerity and nonviolence; they performed sacrifices consisting of rice, barley and oil, but they did not kill the cows". == Yajamana ==
