तत्तस्मान्महतः पापाद्भागमेनोखिलं च वा ।
चितिशक्त्यात्म तत्पुण्यं परिभ्राम्योपशाम्यति ॥ ४ ॥

tattasmānmahataḥ pāpādbhāgamenokhilaṃ ca vā ,
citiśaktyātma tatpuṇyaṃ paribhrāmyopaśāmyati 4

4. Hence any great sin that is committed by any body anywhere, is either partly or wholly effaced by the good act of the person, according to comparative merit of the holy place, or the degree of absolution in the mind of the penitent sinner.
