Bhagwat Gita 4.13
chātur-varṇyaṁ mayā sṛiṣhṭaṁ guṇa-karma-vibhāgaśhaḥ
tasya kartāram api māṁ viddhyakartāram avyayam
Translation
The four categories of occupations were created by me according to people’s qualities and activities. Although I am the creator of this system, know me to be the non-doer and eternal.
