“Krishna is never conquered by anyone, but a devotee can conquer Him through devotional service. As stated in Brahma-samhita (5.33): vedesu durlabham adurlabham atma-bhaktau. One cannot understand Krishna simply by reading Vedic literature. Although all Vedic literature is meant for understanding Krishna, one cannot understand Krishna without being a lover of Krishna.”
(Caitanya-caritamrta Madhya 4.137, Purport)
