पापवल्ली मुखे तस्य जिह्वारूपेण तिष्ठति ।या न वक्ति दिवारात्रौ गुणान्गोविन्दसंभवान् ॥
In plain words
There is a tongue that never speaks, day or night, of the glories that spring from Govinda. In that mouth what stands is no tongue: it is a creeper of sin, rooted there, wearing a tongue's shape.
Close to the Sanskrit
In the mouth of that one a sin-creeper stands in the form of a tongue — the tongue which does not speak, by day or by night, the qualities arising from Govinda.
