The course is complete but it only covers the Eastern wave.
This work is one of the most essential books of the Gauḍīya Vaiṣṇava sampradāya. Śrī Rūpa Gosvāmī establishes in it the theoretical and esoteric foundation of sādhana-bhakti by utilizing the theory of aesthetics (rasa) developed in ancient poetic Sanskrit literature.
In this course, we study the Eastern Division that gives the definition of pure bhakti and expounds its progressive stages from beginning (śraddha, or faith) to perfection of pure love (prema). It is also an erudite exposition of the various rasas. Most important, it also teaches the correct practice of bhakti so that one can get the expected result.
Right now we are busy with our body-mind complex, so we are not free for God. Our mind is full of material attachments and desires. Consequently, there is no room for God. If we invite God into our house, and all of the chairs are occupied, where will he sit? When we make ourself free from our attachments, our suffering and happiness, then our mind will become clear and God can enter.
