“One has to understand the position of prakriti, nature, and purusha, the enjoyer of the nature, and ishvara, the knower who dominates or controls nature and the individual soul. One should not confuse the three in their different capacities. One should not confuse the painter, the painting and the easel. This material world, which is the field of activities, is nature, and the enjoyer of nature is the living entity, and above them both is the supreme controller, the Personality of Godhead.” (Shrila Prabhupada, Bhagavad-gita, 13.3 Purport)
