“In the Gita it is clearly mentioned that material energy works fully under the direction of the Supreme Lord. It has no independent authority. It works as the shadow moves, in accordance with the movements of the object. But still material energy is very powerful, and the atheist, due to his godless temperament, cannot know how it works; nor can he know the plan of the Supreme Lord.” (Shrila Prabhupada, Bhagavad-gita, 7.15 Purport)
