Jñāneśvarī (commentary on the Bhagavadgītā) 4.77

4.77

cāturvarṇyaṃ mayā sṛṣṭaṃ guṇakarmavibhāgaśaḥ
tasya kartāram api māṃ viddhy akartāram avyayam
ātāṃ yāciparī jāṇa |
cārhī āhetī he varṇa |
sṛjile myāṃ guṇa |
karmabhāge ||

Now know this in the very same way: / these four varṇas / were created by Me / according to the division of guṇas and actions.
