Prema bhakti-candrika is popularly known as Sri Rupanuga-gita, as it contains the essence of all the teachings of Lord Caitanya Mahaprabhu. Prema bhakti-candrika literarily means, the rays of the moonlight of loving devotion Sri Krsna. These rays of the moonlight of loving devotion are so soothing that they cool down the effects of the burning fire of material existence, and they enable the conditioned soul to drink the nectar of loving devotional service to Radha and Krsna. Sri Caitanya Mahaprabhu revealed to the world the essence of Krsna-bhakti. He gave to the world what was never given before—love of Krsna, as practiced by the inhabitants of Vrindavana. He instructed the six Gosvamis headed by Srila Rupa and Srila Sanatana to write volumes of devotional scriptures about the nature of love of Krsna. The Gosvamis carried out the instructions of Lord Caitanya Mahaprabhu by writing volumes of devotional scriptures. As an empowered spiritual master who teaches according to time, place and circumstance, Srila Narottama dasa Thakura, took the essence of those writings and composed Prema Bhakti-candrika in a simple style, in the Bengali language. Though these renditions of Sri Caitanya’s teachings appeared simple, the purport is deep. The teachings of Lord Caitanya has thus been given in gist in the form of Sri Prema Bhakti Candrika. The Gosvami’s books that were difficult to understand by the common masses were thus made easily understandable by the teachings of Srila Narottama dasa Thakura in his book—Sri Prema Bhakti-candrika.
