It is like bridge between the humans and other living and non living beings for propelling human consciousness from one trajectory to another sphere of consciousness.
There are various kinds of Yajna. Aptoryama Yajna is the seventh and the biggest of the seven important Soma Yajnas. Aptoryama encompasses performance of an enormous number of rituals and recitation of thousands of Rig, Yajur, Sama and Atharva Veda. In this Yajna 33 oblations of soma juice got out of the creeper is poured as an offerings. This yaga is considered to be the king of the yagas, as soma is the chief offering. This yagas has another important component , Garuda Cayana . The sacrificial fire is central to all Vedic ritual. It is usually lit inside a fire altar made of bricks and/or mud to exacting specifications. The construction of fire altars involved a high level of geometrical and mathematical knowledge. Yajnas of increasing levels of complexity have an increasing number of fire altars.
In Garuda cayana, the main altar for the yajna is constructed with piling of one thousand baked bricks of different shapes and dimensions. The completed altar assumes a shape of an eagle with out stretched wings.
Current study is mainly aimed at understanding the concept of yajna, types of yajna and performance of Aptoryama Yajnas.
