Shri Bhajana Rahasya

In "Shri Bhajana-Rahasya", Bhaktivinoda Thakur systematically describes the various levels of devotion to God, starting from dddhi and ending with prema. While describing the different stages of spiritual development, he bases his reasoning on "Shikshashtaka" and supports his statements with references to "Shrimad Bhagavatam" and works written by the Goswamis.
