Note [1:145:4:4]4. The meaning of svantam, which occurs here and in the obscure passage X, 61, 21 (adha ga'vah upamatim kana'yah anu svantasya kasya kit para iyuh), is unknown. Possibly it is related to svatra, which means something like 'powerful' or 'prosperous.'
Note [1:145:4:5]5. The prayers? The oblations?
Note [1:145:4:6]6. Api-sthitam may have active or passive meaning, 'he who stands on somebody or something,' and 'he on whom somebody or something stands.'
Verse 5.
Note [1:145:5:1]1. The first Pada (and probably also the fourth) belong to the metrical. type described by H. O., Prolegomena, p. 68 seq.: the first part, before the caesura, consists of four syllables; and then the Pada goes on as if it had the pentasyllabic opening.
Note [1:145:5:2]2. After Agni's abode in the Waters and in the wood has been mentioned in the first Pada, the second Pada possibly refers to his heavenly abode to which the adjective upama (highest') seems to point. Thus the 'highest skin' would be the sky. But Sayana, who refers it to the Vedi, may possibly be right. His explanation would very well agree with the second hemistich.
