Srimad Bhagavatham 10:70:43
श्रवणात् कीर्तनाद् ध्यानात् पूयन्ते'न्ते-वसायिनः
तव ब्रह्म-मयस्येश किम् उतेक्षाभिमर्शिनः
Oh Lord the quintessence of absolute truth, even the lowborn become sacred on hearing Your praises, Chanting Your Divine names and glories and by meditating upon you. What then to speak of those who see and touch You?
