That yagna which is performed and offered to the Supreme Lord following the ordinances and injunctions of the Vedic scriptures in the prescribed manner which is compulsory by Vaisnavas and brahmanas for the exclusive satisfaction for the Supreme Lord without any desire for rewards is known to be in sattva guna the mode of goodness. How is this enacted one may ask? It is performed out of duty for its own sake or out of bhakti which is exclusive loving devotion to Lord Krishna or any of His authorised avatars or incarnations and expansions as revealed in Vedic scriptures.
