The material nature, known as māyā, is both the material and efficient cause of the cosmos, but in the background the Lord is the consciousness for all activities. As in the individual body the consciousness is the source of all energies of the body, so the supreme consciousness of the Lord is the source of all energies in material nature. This is confirmed in Bhagavad-gītā (9.10) as follows:

mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram hetunānena kaunteya jagad viparivartate

“Throughout all the energies of material nature there is the hand of the Supreme Lord as the final superintendent. Due to this supreme cause only, the activities of material nature appear planned and systematic, and all thing regularly evolve.”
