In Srila Jiva Goswami’s last purport to his Bhagavat Sandarbha , the Goswami brings out the points of Lord Krishna being  the source of bliss . Although Krishna is blissful, Srila Visvanatha Cakravati Thakur says His bliss is increasingly felt by Him in the association of His pure devotee . Especially , He feels such happiness in the company of the residents of Vraja , and especially the Gopies headed by Srimati Radharani, who is His personified pleasure potency . The source of Srimati Radharani’s pleasure is Krishna . Thus, Krishna comes as Sri Caitanya Mahāprabhu to understand the happiness and bliss Radharani is feeling in His company, the blissful pleasure of pure love that Srimati Radharani feels for Him .There is a competition of love between Radha Krishna, which can be entered into somewhat by the grace of Sri Caitanya Mahāprabhu and Nityananda prabhu, through chanting the Hare Krishna Maha Mantra given by the Gaudia Vaisnava .

Prabhupada frequently emphasized that the Sanskrit verse na tat-samas cabhyadhikas ca drsyate—indicates nobody can be equal to or greater than Krishna. The loving affairs between Radha and Krishna are absolute spiritual exchanges, and within  such exchanges of spiritual love , there is no karma involved , there are no atoms,  elements, or compounds. Soul on soul exchanges of pure love with spiritual forms , eithin a land full of spiritual varigatedness , distinct from ordinary material or romantic relationships. One can never compare cut glass to the highest quality of diamonds.
