Vaishnava Samhita. Dhruvadasa Charitam. Vol II Book VI Chp 7 Shlokas 28 - 29

तमालमूले तत्रैव पतितो मूर्च्छितःशिशुः  |
दिनत्रयमनाहारस्तपश्चक्रे ध्रुवो यथा   ||
वनशोभेक्षणायैवं सञ्चरन्ती सखीजनैः   |
जगतां जननी राधा तं ददर्श यदृच्छया   ||

He fainted there and was lying under a big Tamala tree starving for three days. Thus he was engaged in penance like Dhruva. Unexpectedly Devi Radha, the Mother of the universe, who was going round the forest to enjoy its serene beauty, happened to see him.
