Mahanidhi Madan Gopal Das
“On the day that the jīva accepts śuddha-nāma, one name that he chants certainly destroys the sum total of all his prārabdha and aprārabdha-karma, and through the second name, prema will arise. Those who chant suddha-nama have no desire to perform even pious activities, and what to speak of their maintaining any sinful mentality. A person who has taken shelter of suddha-nama will never commit a sin.” (Jaiva Dharma ch.24)
