सूरदास उवाच

अलं परीक्षया देव जाने नन्दनन्दनम् |

दर्शनं देहि मे शीघ्रमन्धस्य करुणानिधे ||

न मे योगबलं कृष्ण मम नास्ति तपोबलम् |

तथाप्याचार्यकृपया दर्शनं देहि माधव ||

दर्शनं ते दयासिन्धो यदि साक्षान्न लभ्यते ||

तदेयं निष्फला दृष्टिः प्रेतलोकावलोकिनी |

नाहं शोचामि गोविन्द स्मरन् मे नेत्रहीनताम् |

इह लोकादतिक्रम्य भावलोकं गतोस्म्यहम् ||

सुराणां दुर्लभे किन्तु त्वयि साक्षादुपस्थिते |

न पश्यामि कृपासिन्धो नेत्रहीनोस्मि माधव ||

Shri Surdas said

Oh! Deva! Please stop testing me. I have realized that You are Shri Nandakumara Himself. Oh, ocean of compassion! Please give Your darshan to this blind man. I do not have the strength of yoga and tapas. Shri Madhava! Shri Krishna! Please give me Your darshan as I have got the blessings of Shri Vallabha. Oh, ocean of mercy! The eye-sight that is useful to see only the living ghosts (ordinary men) who becomes a waste of Your darshan is not got face to face. Govinda! I do not regret my blindness. For I am wandering in the imaginary land of bliss oblivious to this world. Oh! Ocean of mercy! Madhava! You, who are inaccessible to the devas, are standing in front of me in real form. Yet, I am unable to see You since I am blind.
