CC Ādi 5.206

mora nāma śune yei tāra puṇya kṣaya
mora nāma laya yei tāra pāpa haya
Word for word: 
mora nāma — my name; śune — hears; yei — anyone who; tāra — his; puṇya kṣaya — destruction of piety; mora nāma — my name; laya — takes; yei — anyone; tāra — his; pāpa — sin; haya — is.
Translation: 
Anyone who hears my name loses the results of his pious activities. Anyone who utters my name becomes sinful.
