garbha-nirbharatayā, yathā-
āsanaika-priyasyāsyāḥ sakhī-gātrāvalambinaḥ |
garbhālasasya vapuṣo bhāro' bhūt svāṅga-dhāraṇam ||

From the heaviness of pregnancy, as [in this verse]:
For her body, fond only of sitting, leaning on the limbs of her friend,
and languid with pregnancy, even bearing her own limbs became a burden.
