The chief engineer of a complicated construction does not personally take part in the construction, but he knows every nook and corner because everything is done under his direction. He knows everything about the construction, both directly and indirectly. Similarly, the Personality of Godhead, who is the supreme engineer of this cosmic creation, knows every nook and corner, although affairs are being carried out by demigods. Beginning from Brahmā down to the insignificant ant, no one is independent in the material creation. The hand of the Lord is seen everywhere. All material elements as well as all spiritual sparks emanate from Him only. And whatever is created in this material world is but the interaction of two energies, the material and the spiritual, which emanate from the Absolute Truth, the Personality of Godhead, Śrī Krsna.
