Verse 228

कलिकल्मषमत्युग्रं नरकार्तिप्रदं नृणाम् ।प्रयाति विलयं सद्यः सकृद्यत्रानुसंस्मृते ॥

In plain words

The defilement of the Kali age — savage past measure, and it hands men the torment of hell — dissolves on the spot the moment He is brought to mind, even once.

Close to the Sanskrit

The sin of Kali, exceedingly fierce, bestowing on men the torment of hell, goes at once to dissolution, when He is called to mind even once.
