 As part of the performance of the "Ashvamedha yajna", as mentioned in the "Shatapatha Brahmana", "Asvalayana-srauta-sutra" and "Sankhayana-srauta-sutra", the "Adhvaryu" offered, for the safe movement of the Sacrificial Horse during day-time, three "Istis" daily to "Savitr" and at nightfall performed four "Dhrti Homas" for the safe sheltering of that horse during night-time.While the "Dhrti Homas" were in progress, a "Rajanya" ("Kshatriya") lute-player ("veenagathi") sang three songs ("Gatha") made up of many verses in which he praised the royal-sacrificer with the mention of his heroic exploits, viz., the wars he waged, the battles he won, the conquests he made, so on.The Purana Index lists "Dhrti", borne by "Vijaya", as one of the sons of "Dharma" who was the son of Brahma, and who married all thirteen daughters of "Daksha", each of whom bore "Dhrti" a son.
