ये चैव सात्त्विका भावा राजसास्तामसाश्च ये। मत्त एवेति तान्विद्धि नत्वहं तेषु ते मयि ॥

ye chaiva sāttvikā bhāvā rājasās tāmasāśh cha ye matta eveti tān viddhi na tvahaṁ teṣhu te mayi

The natures that are harmonious, active, slothful, these know as from Me; not I in them, but they in me.

In plain words: Krishna says the three moods of nature—calm goodness, restless activity, and dull laziness—all come from him. They exist within him, but he is not controlled by them.
