The Lord Himself comes to display His transcendental pastimes, typically represented at Vṛndāvana, Mathurā and Dvārakā. He appears just to attract the conditioned souls back to Godhead, back home to the eternal world. But for want of sufficient piety, the onlookers are not attracted by such pastimes of the Lord. In Bhagavad-gītā it is said that only those who have completely surpassed the way of sinful reaction can engage themselves in the transcendental loving service of the Lord. The entire Vedic way of ritualistic performances is to put every conditioned soul on the path of piety. By strict adherence to the prescribed principles for all orders of social life, one can attain the qualities of truthfulness, control of the mind, control of the senses, forbearance, etc., and can be elevated to the plane of rendering pure devotional service to the Lord. Only by such a transcendental vision are one’s material hankerings fully satisfied.
