Process of Devotional Service

Mahāprabhu describes the process of devotional service to Sri Sanatana Goswami. In the beginning He describes the truth about the living entity and the super excellence of devotional service. He then describes the uselessness of mental speculation and mystic yoga. In all circumstances the living entity is recommended to accept the path of devotional service as personally explained by Śrī Caitanya Mahāprabhu. The speculative method of the so-called jñānīs is considered a waste of time, and that is proved in this chapter. An intelligent person should abandon the processes of karma-kāṇḍa, jñāna-kāṇḍa and mystic yoga. There are sixty-four items listed in regulative devotional service, and out of these sixty-four the last five are considered very important.
