Therefore, O Supreme Personality of Godhead, the best of all persons to whom prayers are offered, I offer my respectful obeisances unto You because without rendering six kinds of devotional service unto You — offering prayers, dedicating all the results of activities, worshiping You, working on Your behalf, always remembering Your lotus feet and hearing about Your glories — who can achieve that which is meant for the paramahaṁsas?
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
तत्तेर्हत्तम नमः स्तुतिकर्मपूजाः कर्म स्मृतिश्चरणयोः श्रवणं कथायाम् । संसेवया त्वयि विनेति षडङ्गया किं भक्तिं जनः परमहंसगतौ लभेत
tatterhattama namaḥ stutikarmapūjāḥ karma smṛtiścaraṇayoḥ śravaṇaṃ kathāyām | saṃsevayā tvayi vineti ṣaḍaṅgayā kiṃ bhaktiṃ janaḥ paramahaṃsagatau labheta
