1.4.40.216

yathā hi vā vāsudeveti prokte saṃkīrttane viṣṇubhaktasya vāpi..
smṛte harau vāpi prayāti pāpaṃ satyena me naśyatāṃ tena pāpam.. 42.216 ..

For just as sin departs when 'Vāsudeva' is uttered, / or when chanting by a devotee of Viṣṇu takes place, or when Hari is remembered, by that truth let my sin be destroyed. 42.216
