पुण्यो गन्धः पृथिव्यां च तेजश्चास्मि विभावसौ। जीवनं सर्वभूतेषु तपश्चास्मि तपस्विषु ॥

puṇyo gandhaḥ pṛithivyāṁ cha tejaśh chāsmi vibhāvasau jīvanaṁ sarva-bhūteṣhu tapaśh chāsmi tapasviṣhu

The pure fragrance of earths and the bril liance in fire am I; the life in all beings am I, and the austerity in ascetics.

In plain words: Krishna says he is the sweet smell of the earth and the brightness of fire. He is the life in every being and the self-discipline of those who practice hardship for God.
