श्रीसद्गुरुरुवाच

नन्ददासस्य चरितं परमानन्दवर्धनम् |

शृणुध्वं साधवः सर्वे वक्ष्यामि परमाद्भुतम् ||

दिव्ये बृन्दावने कृष्णो नित्यं क्रीडति माधवः |

विशुद्धप्रेमहृदयाः पश्यन्ति ज्ञानचक्षुषा ||

एतत्तत्वं न जानन्ति मानवा व्यावहारिकाः |

भावलोकं गता भक्ता रमन्ते नन्दसूनुना ||

Shri Sadguru said

Heh! Seers! I shall now narrate to you the life story of Shri Nandadasa. It is capable of enhancing transcendental bliss. Shri Krishna plays in the holy Brindavan eternally. The pious and devoted prema bhakta of Lord Krishna perceive Him with their inner eye of wisdom. The bhaktas, in their state of trance, play happily with Shri Nandadasa. The ordinary men of the world do not realise or understand this.
