tāṅ sabāra - of all of them; nāhi - not; nija-sukha - for their own happiness; anurodha - entreaty; tathāpi - still; bāḍhaye - increases; sukha - happiness; paḍila - happened; virodha - contradiction.

The gopīs have no inclination for their own enjoyment, and yet their joy increases. That is indeed a contradiction.
