Brahma Yajna is Svadhyaya, that is to say, intense study and observance of the Veda. The Rishis who were ‘unborn’ and therefore authorised by Brahman to transmit the truth, formulated, according to the visions they earned, the Yajnas or sacrificial rites designed to promote peace and prosperity in the world. The Vedas acknowledge as Rishis, only those who treasure in their hearts the awareness of mantras, of the Supreme truth, and of the meaning and significance of Brahman (the Cosmic Self) and Dharma (the Laws of Social Harmony and Individual Rights and Duties). The ritual sacrifices authorised and accepted by the Rishis are called ‘Yajnas’. (LKV, p. 15)
