YajnaYajna (yajña) refers in Hinduism to any ritual done in front of a sacred fire, often with mantras. Yajna has been a Vedic tradition, described in a layer of Vedic literature called Brahmanas, as well as Yajurveda. The tradition has evolved from offering oblations and libations into sacred fire to symbolic offerings in the presence of sacred fire (Agni). Yajna rituals-related texts have been called the Karma-kanda (ritual works) portion of the Vedic literature, in contrast to Jnana-kanda (knowledge) portion contained in the Vedic Upanishads.
NairThe Nair (ˈnaɪər, n̪aːjɐr) also known as Nayar, are a group of Indian Hindu castes, described by anthropologist Kathleen Gough as "not a unitary group but a named category of castes". The Nair include several castes and many subdivisions, not all of whom historically bore the name 'Nair'. These people lived, and continue to live, in the area which is now the Indian state of Kerala. Their internal caste behaviours and systems are markedly different between the people in the northern and southern sections of the area, although there is not very much reliable information on those inhabiting the north.
