15.13

गामाविश्य च भूतानि
धारयाम्यहमोजसा ।
पुष्णामि चौषधीः सर्वाः
सोमो भूत्वा रसात्मकः ॥

gām āviśya ca bhūtāni dhārayāmy aham ojasā
puṣṇāmi cauṣadhīḥ sarvāḥ somo bhūtvā rasātmakaḥ

Kṛṣṇa (कृष्ण) continues, in the first person, as the one who holds beings and feeds the plants.

The verse

And entering the earth I support beings by my vigor, and having become the moon whose self is sap I nourish all the plants.

नेपालीमा

र पृथ्वीमा पसेर म आफ्नो ओजले प्राणीहरूलाई धान्छु, र रस नै स्वरूप भएको चन्द्रमा बनेर म सबै वनस्पति पाल्छु।

Where it sits

The light of 15.12 becomes a hold and a feeding. Earth and moon are not a new subject beside him. He enters, he supports, he becomes the sap and nourishes. The fire inside the body is next.

The phrases

गाम् आविश्य च भूतानि धारयामि अहम् ओजसा gām āviśya ca bhūtāni dhārayāmi aham ojasā is the hold on creatures. Having entered the earth, I support beings by my vigor. गाम् + आविश्य gām + āviśya is gām āviśya (गामाविश्य). धारयामि + अहम् dhārayāmi + aham is dhārayāmy aham (धारयाम्यहम्), and अहम् + ओजसा aham + ojasā is aham ojasā (अहमोजसा).

puṣṇāmi ca oṣadhīḥ sarvāḥ (पुष्णामि च ओषधीः सर्वाः) is the feeding. And I nourish all the plants. च + ओषधीः ca + oṣadhīḥ is cauṣadhīḥ (चौषधीः), अ + ओ a + o becoming au (औ).

somaḥ bhūtvā rasātmakaḥ (सोमः भूत्वा रसात्मकः) is how the feeding is done. Having become the moon, whose nature is sap. सोमः + भूत्वा somaḥ + bhūtvā is somo bhūtvā (सोमो भूत्वा). रस + आत्मकः rasa + ātmakaḥ is rasātmakaḥ (रसात्मकः).

Sanskrit in this line

go (गो) "earth" has the accusative gām (गाम्), and that is the form in this line, not गाम् dropped to a shorter guess. āviśya (आविश्य) is the gerund of a prefixed verb, so --ya (य). The subject of āviśya (आविश्य) and of bhūtvā (भूत्वा) is aham (अहम्), the subject of both finite verbs.

Say it back

What he enters, what he holds, and what he becomes in order to feed the plants. If somaḥ (सोमः) is only a drink and not the moon he becomes, stay here.
