मयाऽध्यक्षेण प्रकृतिः सूयते सचराचरम्। हेतुनाऽनेन कौन्तेय जगद्विपरिवर्तते ॥

mayādhyakṣheṇa prakṛitiḥ sūyate sa-charācharam hetunānena kaunteya jagad viparivartate

Under Me as supervisor, Nature sends forth the moving and unmoving: because of this, O Kaunteya, the universe revolves.

In plain words: Krishna says nature produces everything that moves and everything that stays still, while he watches over it. Because of this, the world keeps turning.
