Vaishnava Samhita. Narasimha Mehta Charitam I. Vol III Book VI Chp 15 Shlokas 47 - 48

सद्यः प्रेमसमाक्रान्तः कृष्णप्रेमवशीकृतः  |
ददर्श तत्र चात्मानं गोपीरूपेण संश्तितम्  ||
कृष्णचन्दनलिप्ताङ्गं कृष्णालिङ्गनमोहितम् | 
कृष्णशिक्षितनाट्यञ्च कृष्णकीर्तनतत्परम्  ||

The very moment Narasimha Mehta felt a transformation in him. He found himself to be a Gopi. He was enchanted by the prem of Shri Krishna. He felt himself perfected with loving devotion. His body seemed as though rubbed with the same sandal paste of Shri Krishna. He was intoxicated with the embrace of Shri Krishna. He was to be dancing in the manner taught by Shri Krishna. He too was immersed in Krishna kirtan.
