v. 7 (xxii. 2). Here they chant the Mahānāmnī verses to the Çākvara Sāman; on the Rathantara day, the fifth day, it is a symbol of the fifth day. By them Indra fashioned himself as great; therefore are they called Mahānāmnīs; moreover these worlds are the Mahānāmnīs and these are great. Having created these worlds Prajāpati had all power whatever there is here. In that having created these worlds Prajāpati had all power whatever there is here, therefore they become the Çakvarī verses; that is why the Çakvarīs have the name (powerful). Beyond the boundary he created them; so that he created them beyond the boundary, they became the Sīmās; that is why the Sīmās have their name. ‘Of the sweet thus diffused’, ‘To our pressed drink with the dappled steeds’, and ‘Indra all made grow’ are the antistrophe; as containing (the words) ‘strong’, ‘dappled’ ‘be drunk’ and ‘grow’ on the fifth day it is a symbol of the fifth day. ‘What he hath won’ is the normal inserted verse. In ‘Towards thee, O hero, we utter praise’ he makes to follow the basis of the Rathantara; for this day is connected with the Rathantara in place. ‘Not then any of thy worshippers’ is the Pragātha of the Sāman; as having an addition it is on the fifth day a symbol of the fifth day. ‘This steed, god strengthened’ is the normal Tārkṣya (hymn).
