v. 7. 26.

Agni was the animal; with it they sacrificed; it won this world where Agni is; this is thy world, thou wilt win it, and so snuff (it).
Vayu was the animal; with it they sacrificed; it won this world where Vayu is; this is thy world, therefrom will I obstruct thee if thou dost not snuff (it).
Aditya was the animal; with it they sacrificed; it won this world where Aditya is; this is thy world, thou wilt win it if thou dost snuff it.
