The Vedas inform us:

Nārāyaṇa, the Supreme Personality of Godhead, is almighty, omnipotent. He has multifarious energies, and therefore He is able to remain in His own abode and without endeavor supervise and manipulate the entire cosmic manifestation through the interaction of the three modes of material nature— sattva-guṇa, rajo-guṇa and tamo-guṇa. These interactions create different forms, bodies, activities and changes, which all occur perfectly. Because the Lord is perfect, everything works as if He were directly supervising and taking part in it. Atheistic men, however, being covered by the three modes of material nature, cannot see Nārāyaṇa to be the supreme cause behind all activities. As Kṛṣṇa says in Bhagavad-gītā (7.13):"Deluded by the three modes, the whole world does not know Me, who am above the modes and inexhaustible." Because unintelligent agnostics are mohita, illusioned by the three modes of material nature, they cannot understand that Nārāyaṇa, Kṛṣṇa, is the supreme cause of all activities. As stated in Brahma-saṁhitā (5.1): "Kṛṣṇa, who is known as Govinda, is the supreme controller. He has an eternal, blissful, spiritual body. He is the origin of all. He has no other origin, for He is the prime cause of all causes."
