Formerly there were kings like Jarasandha who strictly followed the Vedic rituals, acted as charitable, competent ksatriyas, possessed all ksatriya qualities and were even obedient to the brahminical culture but who did not accept Krsna as the Supreme Personality of Godhead. Jarasandha attacked Krsna many times, and each time, of course, he was defeated. Like Jarasandha, any man who performs Vedic rituals but does not accept Krsna as the Supreme Personality of Godhead must be considered an asura, or demon. Similarly, one who does not accept Sri Caitanya Mahaprabhu as Krsna Himself is also a demon. This is the conclusion of authoritative scriptures. Therefore, both so-called devotion to Gaurasundara without devotional service to Krsna and so-called krsna-bhakti without devotional service to Gaurasundara are nondevotional activities. If one wants to be successful on the path of Krsna consciousness, he must be thoroughly conscious of the personality of Gaurasundara as well as the personality of Krsna. Knowing the personality of Gaurasundara means knowing the personalities of sri-krsna-caitanya prabhu-nityananda sri-advaita gadadhara srivasadi-gaura-bhakta-vrnda. The author of Sri Caitanya-caritamrta, pursuant to the authorities, stresses this principle for perfection in Krsna consciousness.
