Whenever any one has had problems in life and approached Gurudev, Gurudev has one very central advice - please bury your head in reading Srimad Bhagavatam and do not look up. Dig your heels in and hear Srimad Bhagavatam!
Lord Sri Caitanya Mahaprabhu, to show to the world, the magnanimity of His dearest devotees, have talks and discussions at times with them. From these transcendental talks, questions and answers, we get a very good idea about devotional service, the Lord and His devotees and many other things.
And as Srila Prabhupada says in several places in his purports, that those instructions sometimes come from the paramatma within, and also from the Spiritual master externally. The choice is with us to either follow them or not.
