It is said, tretÄyÄá¹ yajato makhaiḥ: in TretÄ-yuga, if one performed yajñas, he would get the results of those yajñas. By performing viṣṇu-yajña specifically, one could even achieve the lotus feet of the Supreme Personality of Godhead. Of course, yajña is intended to please the Supreme Personality of Godhead. While PurÅ«ravÄ was meditating upon Urvaśī, the TretÄ-yuga began, and therefore the Vedic yajñas were revealed in his heart. But PurÅ«ravÄ was a materialistic man, especially interested in enjoying the senses. Yajñas for enjoyment of the senses are called karma-kÄṇá¸Ä«ya-yajñas. Therefore, he decided to perform karma-kÄṇá¸Ä«ya-yajñas to fulfill his lusty desires. In other words, karma-kÄṇá¸Ä«ya-yajñas are meant for sensuous persons, whereas yajña should actually be performed to please the Supreme Personality of Godhead. To please the Supreme Personality of Godhead in Kali-yuga, the saá¹…kÄ«rtana-yajña is recommended. Yajñaiḥ saá¹…kÄ«rtana-prÄyair yajanti hi sumedhasaḥ. Only those who are very intelligent take to saá¹…kÄ«rtana-yajña to fulfill all their desires, material and spiritual, whereas those who are lusty for sense enjoyment perform karma-kÄṇá¸Ä«ya-yajñas.
