श्रीसद्गुरुरुवाच 
श्रीवल्लभस्ततो लोके सर्वशास्त्रविशारदः |
शमादिगुणसंपन्नो विरक्तो विजितेन्द्रियः  ||
कृततीर्थाटनो नित्यं ब्रह्मचर्यव्रते स्थितः  |
यदृच्छालाभसन्तुष्टो कृष्णध्यानपरायणः  || 
श्रीमद्भागवतेनैव कृष्णभक्तिं प्रचारयन्  |
उत्तमे भारते देशे प्रतिग्रामं चचार सः  ||

Shri Sadguru said

Shri Vallabha, an adept in all Shastras, the man endowed with all noble qualities like modesty, vairagya and complete control over his senses. The celibate who was contented with his lot and was ever engaged in Krishna dyana went on a long pilgrimage. Visiting every village in the country,he rooted Krishna bhakti firmly through his discourses on the Shrimad Bhagavatam.
