7.9

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

puṇyo gandhaḥ pṛthivyāṃ ca tejaś cāsmi vibhāvasau
jīvanaṃ sarvabhūteṣu tapaś cāsmi tapasviṣu

Kṛṣṇa (कृष्ण) is speaking, to Arjuna (अर्जुन). The sentence is still the "I am" of 7.8.

The verse

And I am the pure smell in the earth, the brilliance in fire, the life in all beings, and the austerity in those who practice it.

नेपालीमा

अनि म पृथ्वीमा शुद्ध गन्ध हुँ, आगोमा तेज हुँ, सबै भूतमा जीवन हुँ, र तप गर्नेहरूमा तप हुँ।

Where it sits

7.8 put him in water, moon and sun, Veda, space, and men. This verse finishes that kind of list: earth, fire, living beings, the person under austerity. The next verse changes the shape, from "I am the quality in the thing" to "know me as the seed."

Split: पुण्यः + गन्धः + पृथिव्याम् + च + तेजः + च + अस्मि + विभावसौ + जीवनम् + सर्व-भूतेषु + तपः + च + अस्मि + तपस्विषु

The phrases

puṇyaḥ gandhaḥ pṛthivyām (पुण्यः गन्धः पृथिव्याम्) is one pair. He is not every smell in the earth. He is the pure one. puṇyaḥ (पुण्यः) is doing that limiting.

tejaḥ asmi vibhāvasau (तेजः अस्मि विभावसौ) is the brilliance in fire. jīvanam sarva-bhūteṣu (जीवनम् सर्व-भूतेषु) is the life in every being, the same life the higher nature was said to be in 7.5. tapaḥ tapasviṣu (तपः तपस्विषु) is the austerity in the people who keep it.

Sanskrit in this line

tejaḥ (तेजः) and tapaḥ (तपः) are nominatives of stems in --s (स्). Before ca (च), that visarga becomes ś (श्), the same change as कः + चित् kaḥ + cit in 7.3.

तेजः + च + अस्मि tejaḥ + ca + asmi is recited tejaś cāsmi (तेजश्चास्मि). First aḥ (अः) before c (च्) becomes aś (अश्). Then च + अस्मि ca + asmi becomes cāsmi (चास्मि), because अ + अ a + a becomes ā (आ). तपः + च + अस्मि tapaḥ + ca + asmi does it again: tapaś cāsmi (तपश्चास्मि). The asmi (अस्मि) is inside the cluster. Do not lose the "I am."

Say it back

Four pairs. The smell has to stay the pure smell. If puṇyaḥ (पुण्यः) drops, the verse says he is smell in general, and that is not the line.
