Vaishnava Samhita. Katha Sangraham. Vol III Book VI Chp 25 Shlokas 17 - 20

षोडशे कन्याकाशुल्कं ददौ लब्ध्वा धनं सताम् |
नरसिह्मस्तस्य सत्यञ्चक्रे श्रियः पतिः || 
पितृश्राद्धं सप्तदशे चकार च हरिः स्वयम् |
बृन्दावनं गते तस्मिन् लोकवेदपराङ्ग्मुखे ||
एवमष्टादशाध्याये कृष्णदासो दृढव्रतः |
बृन्दावनं परित्यज्य प्रपेदे द्वारकापुरीम् ||
एकोनविंशे भक्तस्य स्वयं प्रेमनिधेर्मुदा |
दर्शयामास मार्गञ्च रात्रौ करुणया हरिः ||   

Chapter Sixteen explains this incident. Shri Narasimha Mehta used the money entrusted to him by the sdhus to give dowry in his daughter's marriage. Later Lord Shripati fulfilled the promise of Shri Mehta. As per Chapter Seventeen Mehta left for Shri Brindavan forgetting the worldly code and the prescriptions of the Vedas. So Lord Hari Himself performed the shraddha ceremony of his father. Chapter Eighteen decribes how the determined Krishnadas left Shri Brindavan and reached Dwaraka. The Nineteenth Chapter deals with the incident of Shri Krishna accompanying His devotee Premanidhi and showing the right path to him in the dark night due to His untold mercy.
