In Bhagavad-gītā it is said that when the Lord descends to this material world, He comes as a person by His own energy, ātma-māyā. He is not forced by any superior energy. He comes by His own will, and this can be called His pastime, or līlā. But here it is clearly stated that the conditioned soul is forced to take a certain type of body and senses under the three modes of material nature. That body is not received according to his own choice.
