Bhagavad Gita 7.12 — Three gunas come from God
ये चैव सात्त्विका भावा राजसास्तामसाश्च ये। मत्त एवेति तान्विद्धि न त्वहं तेषु ते मयि ॥
ye caiva sāttvikā bhāvā rājasāstāmasāśca ye | matta eveti tānviddhi na tvahaṃ teṣu te mayi ||
Meaning
Know that all states of being — sattvic, rajasic and tamasic — come from me alone. Yet I am not in them; they are in me.
