^4:1 The commentator translates: 'I tell it thee, attend to me who knows the heavenly fire.' Here the nom. sing. of the participle would be very irregular, as we can hardly refer it to bravimi. Then, 'Know this fire as a means of obtaining the heavenly world, know that fire as the rest or support of the world, when it assumes the form of Virag, and as hidden in the heart of men.'

^4:2 Sankara: the first embodied, in the shape of Virag.

^5:1 Verses 16-18 seem a later addition.

^5:2 This arises probably from a misunderstanding of verse 11, 3.

^5:3 Gatavedas.

^5:4 Tavaiva is a later addition, caused by the interpolation of verses 15-18.

^6:1 Mahabhumau, on the great earth, has been explained also by maha bhumau, be great on the earth. It is doubtful, however, whether mahi for mahin could be admitted in the Upanishads, and whether it would not be easier to write mahan bhumau.

^7:1 A very obscure verse. Sankara gives a various reading kva tadasthah for kvadhahsthah, in the sense of I given to these pleasures,' which looks like an emendation. I have changed agiryatam into agaryatam, and take it for an acc. sing., instead of a gen. plur., which could hardly be governed by upetya.
