The Fourth Chapter is summarized by Bhaktivinoda Ṭhākura in his Amṛta-pravāha-bhāṣya as follows. Śrīla Sanātana Gosvāmī came alone from Mathurā to Jagannātha Purī to see Lord Caitanya. Because of bathing in bad water and not getting enough food every day while traveling on the path through Jhārikhaṇḍa (Jharkhand) Forest, he developed a disease that made his body itch. Suffering greatly from this itching, he resolved that in the presence of Śrī Caitanya Mahāprabhu he would throw himself under the wheel of Jagannātha's car and in this way commit suicide.
When Sanātana Gosvāmī came to Jagannātha Purī, he stayed under the care of Haridāsa Ṭhākura for some time, and Śrī Caitanya Mahāprabhu was very happy to see him. The Lord informed Sanātana Gosvāmī about the death of his younger brother Anupama, who had great faith in the lotus feet of Lord Rāmacandra. One day Śrī Caitanya Mahāprabhu said to Sanātana Gosvāmī, "Your decision to commit suicide is the result of the mode of ignorance. One cannot get love of God simply by committing suicide. You have already dedicated your life and body to My service; therefore your body does not belong to you, nor do you have any right to commit suicide. I have to execute many devotional services through your body. I want you to preach the cult of devotional service and go to Vṛndāvana to excavate the lost holy places." After having thus spoken, Śrī Caitanya Mahāprabhu left, and Haridāsa Ṭhākura and Sanātana Gosvāmī had many talks about this subject.
