Chapter 4: Sloka 13

4.13

cātur-varṇyaṁ mayā sṛṣṭaṁ
guṇa-karma-vibhāgaśaḥ
tasya kartāram api māṁ
viddhy akartāram avyayam

cātur-varṇyam—the four divisions of human society; mayā—by Me; sṛṣṭam—created; guṇa—quality; karma—work; vibhāgaśaḥ—in terms of division; tasya—of that; kartāram—the father; api—although; mām—Me; viddhi—you may know; akartāram—as the non-doer; avyayam—being unchangeable.

According to the three modes of material nature and the work ascribed to them, the four divisions of human society were created by Me. And, although I am the creator of this system, you should know that I am yet the non-doer, being unchangeable.
