It is personally experienced by me that those who are always full of cares and anxieties due to desiring contact of the senses with their objects can cross the ocean of nescience on a most suitable boat — the constant chanting of the transcendental activities of the Personality of Godhead.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
प्रगायतः स्ववीर्याणि तीर्थपादः प्रियश्रवाः । आहूत इव मे शीघ्रं दर्शनं याति चेतसि
pragāyataḥ svavīryāṇi tīrthapādaḥ priyaśravāḥ | āhūta iva me śīghraṃ darśanaṃ yāti cetasi
