Kṛṣṇa (कृष्ण) is still speaking, to Arjuna.

The verse

Others offer all the actions of the senses and of the breaths into the fire of the yoga of self-restraint, kindled by knowledge.

नेपालीमा

अरूहरूले इन्द्रियका र श्वासका सबै कर्म ज्ञानले बालिएको आत्मसंयमको योगको आगोमा चढाउँछन्।

The phrases

sarvāṇi indriyakarmāṇi prāṇakarmāṇi ca apare (सर्वाणि इन्द्रियकर्माणि प्राणकर्माणि च अपरे) is what is offered, and who offers it. Others offer all the actions of the senses and the actions of the breaths. sarvāṇi indriya (सर्वाणि इन्द्रिय) is sarvāṇīndriya (सर्वाणीन्द्रिय). ca apare (च अपरे) is cāpare (चापरे).

ātmasaṃyamayogāgnau juhvati jñānadīpite (आत्मसंयमयोगाग्नौ जुह्वति ज्ञानदीपिते) is the fire. They offer them into the fire of the yoga that holds the self, and that fire is kindled by knowledge. agnau (अग्नौ) and dīpite (दीपिते) are both locative. The participle describes the fire, not the people.

Sanskrit in this line

jñānadīpite (ज्ञानदीपिते) agrees with agnau (अग्नौ), locative singular. A describing word takes the case of the word it describes, not the case of the people offering. If you read dīpite (दीपिते) as a nominative, it has no noun to agree with. The fire is what is kindled. The people are apare (अपरे), and their verb is juhvati (जुह्वति).

Say it back

What is offered, and which fire receives it. If jñānadīpite (ज्ञानदीपिते) is said of the sacrificers, stay here.
