न मन्त्रेण न संस्कारात् कुलेनापि न वैष्णवः |
विष्णुभक्तिर्यदि दृढा स हि श्रीवैष्णवोत्तमः ||
महतां वैष्णवानां तु कुले जातो यदृच्छया |
न करोति हरौ भक्तिं यदि नीचाधमः स्मृतः ||
One is not considered a vaishnava because of high birth or adherence to rituals or knowledge of mantras. One who has unwavering Vishnu bhakti alone becomes a vaishnavottama. One who is born in a reputed vaishnava clan and yet fails to develop Hari bhakti is really considered a low-born.
