6.2.18

अज्ञानादथवा ज्ञानादुत्तमश्लोकनाम यत् । सङ्कीर्तितमघं पुंसो दहेदेधो यथानल: ॥ १८ ॥

uttamasloka
of the Supreme Personality of Godhead

As a fire burns dry grass to ashes, so the holy name of the Lord, whether chanted knowingly or unknowingly, burns to ashes, without fail, all the reactions of one’s sinful activities.
