Vaishnava Samhita. Raskhan Charitam. Vol III Book VII Chp 13 Shlokas 29 -31

अप्राप्य नीलबालस्य दर्शनं सुरदुर्लभम् |

विरहेण व्याकुलोsयं यवनो मूर्च्छितोsभवत् ||

आकर्ण्य चेष्टितं तस्य विट्ठलेशः कृपानिधिः |

द्रष्टुं तमाययौ शीघ्रं महाभागवतोत्तमम् ||

तं दृष्ट्वा विट्ठलेशञ्च यवनो हर्षपूर्वकम् |

उत्थाय प्रार्थयामास गृहीत्वा तत्पदाम्बुजम् ||

Failing to get the darshan of the 'Neelbala' Shri Krishna, which is not easily attained even by the devas, Raskhan became desperate. He fainted stricken with the grief of total distance from Shri Krishna. Shri Vitthalantha came to know of all these happenings. That most compassionate and distinguised bhagavata rushed to Shri Brindavan to see Raskhan. When Raskhan saw Shri Vitthalanatha, he became very happy and got up immediately. Catching hold of that noble man's feet, he started pleading.
