Srimad Bhagavatham 2:1:11
एतन् निर्विद्यमानानाम् इच्छताम् अकुतो-भयम्
योगिनां नृप निर्णीतं हरेर् नामानुकीर्तनम्
O King! For those devotees who have lost all their attachments to worldly objects, for those seeking salvation from fear and afflictions, for those desirous of enjoying the various fruits of their actions and also for those men of wisdom delighted in themselves (Atmaram), the only certain course for success declared unanimously by all the sages of yore is the hearing, chanting, and meditation of the Glory of the Divine Name of Sri Hari.
