6.6.1.8

eka eṣa bhavati | ekadevatya ekasthaṃ tatkṣatramekasthāṃ śriyaṃ karoti caruritaro bahudevatyo bhūmā vā eṣa taṇḍulānāṃ yaccarurbhūmo eṣa devānāṃ yadādityā viśi tadbhūmānaṃ dadhātītyadhidevatam

That (Vaisvânara cake) is one single (oblation), having one single deity: he thus makes the ruling power to be concentrated in one (person), and excellence to be concentrated in one. The other, the pap, has many deities, for the pap is a multiplicity of rite-grains, and those Âdityas are a multiplicity of gods: he thus bestows multiplicity on the people. Thus much as to the deities.
