The actual purpose of the Lords creation is only one.
According to Śrīla Jīva Gosvāmī, the actual purpose of the Lord’s creation is only one: to facilitate the advancement of devotional service to the Lord Himself. Although it is stated that the Lord facilitates sense gratification, it should be understood that the Supreme Personality of Godhead does not ultimately condone the foolishness of the conditioned souls. The Lord facilitates sense gratification (mātrā-prasiddhaye) so that the living entities will gradually understand the futility of trying to enjoy without Him. Every living entity is part and parcel of Kṛṣṇa. In the Vedic literature the Lord gives a regulative program so that the living beings can gradually exhaust their tendencies to be foolish and learn the value of surrender unto Him. The Lord is undoubtedly the reservoir of all beauty, bliss and satisfaction, and it is the duty of every living entity to engage in the loving service of the Lord. Although there are apparently two purposes for creation, it should be understood that ultimately the purpose is one. The arrangement for sense gratification is ultimately meant to bring the living entities to the single purpose of going back home, back to Godhead.
