I am the pure fragrance in the earth, the brilliance in fire, the life in all beings, and the austerity in ascetics.

Continuation of the immanent vision: puṇyaḥ gandhaḥ (pure/sacred fragrance) of the earth — not the chemical essence but the divine quality. Tejas (brilliance, energy) of fire (vibhāvasau).

Jīvanam (vitality, living principle) in all beings — connected with parā prakṛti (7.5). And tapas (heat, austerity, spiritual energy) in tapasvin (ascetics).
