Unless one understands the conclusions of Bhagavad Gita, which is “Man mana bhava mad bhakto “
“Think of me and become my devotee.” These are the words of Krishna.
How to think of Krishna ? Absorbed in the topmost levels of pure love in deep meditation is demonstrated by Sri Caitanya Mahāprabhu in his absorption of the mood of Srimati Radharani , damsels of Vraj and their young assistants the Manjaris. This truth of the life that Mahāprabhu experienced was taught the Goswamis of Vrndavana , headed by Srila Rupa Ragganatha, and they and their followers record and delineate everything in their writings . One may miss out on the essence of Mahaprabhu’ purposes for appearing and get caught up in the many peripheral aspects of a progressive path of spiritual life , things that Mahāprabhu recognised in his conversation with Ramananda Roy , but kept saying ” this is good but is there more “or ” that is also good but is there more”
Everything of this conversation is in the Caitanya Caratamrita and Srila AC Bhaktivedanta Swami Prabhupada has translated it to English along with explanations to all the peripherals and the essence of Bhakti yoga
