वसन् कदम्बवृक्षस्य मूले गोवर्धनान्तिके |

चकार भक्तिं सुदृढां श्रीनाथपदपङ्कजे ||

सख्यभावेन संयुक्तः शुद्धप्रेमरसेन सः |

चक्रे बहुविधा लीलाः कृष्णेन परमात्मना ||

तद्भक्तिवशमापन्नो भगवान् श्यामसुन्दरः |

चकार लीलां विविधां साक्षाद्दर्शनमागतः ||

सन्ततं विहरंस्तत्र गोवर्धनमहावने |

बभूवोन्मत्तवद्भक्तः श्रीनाथेन दिने दिने ||

He made the foot of a Kadambara tree in the area surrounding Govardhana Hill as his dwelling place. He spent his time in nurturing unflinching devotion to the holy feet of Shrinatha. He developed a sentiment of friendly love (sakhya prem) for Shri Krishna, and got engaged in many kinds of divine pastimes with the Supreme Soul. Bhagavan, Shri Krishna came under the spell of his devotion, and hence He gave darshan to Govindadasa. Shri Bhagavan engaged in many sports with him coming in His true form. Daily that bhakta used to play happily with Shrinatha in the forest situated under the foot of Govardhana Hill. He appeared to be almost a lunatic.
