CC Ādi 16.71
doṣa-yuk ced vibhūṣitam
syād vapuḥ sundaram api
rasa — with humors; alaṅkāra-vat — with ornaments (metaphors, similes, etc.); kāvyam — poetry; doṣa-yuk — faulty; cet — if; vibhūṣitam — very nicely decorated; syāt — it becomes so; vapuḥ — the body; sundaram — beautiful; api — even though; śvitreṇa — by a white spot of leprosy; ekena — one; durbhagam — unfortunate.
“ ‘As one’s body, although well-decorated with ornaments, is made unfortunate by even one spot of white leprosy, so an entire poem is made useless by a fault, despite alliteration, similes and metaphors.’
