Vaishnava Samhita. Shri Kumbhaadasa Charitam. Vol III Book VII Chp 7 Shlokas 6 - 7

अस्य वैष्णवधर्मस्य बहवो मार्गदर्शिनः |

तत्रैकः कुंभदासश्च महाभागवतः स्मृतः ||

शिष्यः श्रीवल्लभेन्द्रस्य सर्वसद्गुणसंयुतः |

श्रीनाथचरणाम्भोजमकरन्दमधुव्रतः ||

Many progenitors are there, who have paved the path of Vaishnava Dharma. Kumbhadasa, the great bhagavata, was one among them. He was endowed with all noble qualities. He was a disciple of Shri Vallabha, and was whirling round the lotus feet of Shrinatha like a bee.
