The commentators
Bhagavadgītābhāṣyam
किञ्च —
सर्वाणि इन्द्रियकर्माणि इन्द्रियाणां कर्माणि इन्द्रियकर्माणि, तथा प्राणकर्माणि प्राणो वायुः आध्यात्मिकः तत्कर्माणि आकुञ्चनप्रसारणादीनि तानि च अपरे आत्मसंयमयोगाग्नौ आत्मनि संयमः आत्मसंयमः स एव योगाग्निः तस्मिन् आत्मसंयमयोगाग्नौ जुह्वति प्रक्षिपन्ति ज्ञानदीपिते स्नेहेनेव प्रदीपे विवेकविज्ञानेन उज्ज्वलभावम् आपादिते जुह्वति प्रविलापयन्ति इत्यर्थः ॥ २७ ॥
In plain words
And there is more —
'All the sense-functions' means simply the functions belonging to the senses; likewise 'the functions of prāṇa' — prāṇa here is the inward breath, and its functions are contracting, extending, and so on. These, and other things besides, they pour into the fire of self-mastery through yoga: restraint fixed in the Self is what is meant by self-restraint, and that restraint is itself the fire of yoga. Into that fire they offer, they cast in — as if pouring oil into a lamp already lit by knowledge and brought to full brilliance by discriminative insight — they offer them there, meaning they let them simply dissolve away. That is the meaning.

And what more —
'All the sense-functions' — the functions of the senses, the sense-functions; likewise 'the functions of prāṇa' — prāṇa is the inward vital breath; its functions are contraction, extension, and the like. Those, and others, they offer into the fire of the yoga of self-restraint — restraint in the Self is called self-restraint; that itself is the fire of yoga; into that fire of the yoga of self-restraint they offer, cast in — into a lamp kindled by knowledge, as if by oil, brought to full brilliance by discriminative insight — they offer them, that is, they cause them to dissolve. This is the meaning.
