The instructions and teachings of Lord Caitanya are very important for people in general. He teaches the process of devotional service, which is the constitutional occupation of every living entity, for it is every man's duty to advance in spiritual science. Many subjects were thoroughly discussed in the talks between Lord Caitanya and Sanātana Gosvāmī. Due to the mercy of Lord Caitanya, Sanātana was able to put important questions before Him, and these questions were replied to properly.
By the meeting of Sanātana and Lord Caitanya, we learn that in order to understand spiritual subject matters, one must approach a spiritual master like Lord Caitanya Mahāprabhu and make submissive inquiries. It is also confirmed in Bhagavad-gītā (BG 4.34) that one should approach a man of authority and learn the science of spiritual life from him.
