Verse
मयाध्यक्षेण प्रकृतिः सूयते सचराचरम् ।हेतुनानेन कौन्तेय जगद्विपरिवर्तते ॥
I am the presiding control of my own action of Nature, (not a spirit born in her, but) the creative spirit who causes her to produce all that appears in the manifestation. Because of this, O Kaunteya, the world proceeds in cycles.
Gītā 9·10
