SB 10.42.1
striyaṁ gṛhītāṅga-vilepa-bhājanām
vilokya kubjāṁ yuvatīṁ varānanāṁ
papraccha yāntīṁ prahasan rasa-pradaḥ
According to Śrīla Viśvanātha Cakravartī Ṭhākura, the young hunchbacked girl was actually a partial expansion of the Lord’s wife Satyabhāmā. Satyabhāmā is the Lord’s internal energy known as Bhū-śakti, and this expansion of hers, known as Pṛthivī, represents the earth, which was bent down by the great burden of countless wicked rulers. Lord Kṛṣṇa descended to remove these wicked rulers, and thus His pastime of straightening out the hunchback Trivakrā, as explained in these verses, represents His rectifying the burdened condition of the earth. At the same time, the Lord awarded Trivakrā a conjugal relationship with Himself.
In addition to the given meaning, the word rasa-pradaḥ indicates that the Lord amused His cowherd boyfriends by His dealings with the young hunchback.
