SB 1.11 - What motivates Kṛṣṇa to act?

In this world a person’s motivation to act is impelled by personal shortcomings. If one did not need anything, one would not need to act, because action is meant to obtain what one lacks. Could Kṛṣṇa lack something that makes Him engage in activities? SB 1.11.35 says that Kṛṣṇa, out of causeless mercy, appeared on this planet by His internal potency, the yoga-māyā, and He enjoyed among the best of women by expanding Himself according to His nature. As confirmed in SB 1.10.24, the Lord acts in this universe for His own līlā (jagad-ātma-līlayā). The Lord’s living like a householder and enjoying may appear like He is engaged in mundane affairs. But it is not so. The causes of the Lord’s enjoyment, the desire to enjoy and the activities of enjoyment are all beyond the guṇas because He is not material. When the Lord appears in different places, He displays His pastimes to attract the conditioned souls. Conditioned souls seek after perpetual happiness in all places. But when he fails and comes to his senses, he seeks after Brahman happiness knowing that the happiness he is seeking cannot be found in the material world. As such, Parabrahman certainly does not seek happiness anywhere in the material world. Thus the activities of the Lord is not mundane affair but belong to the transcendental realm.
