I am preparing the Sequence of Articles about Shree MoolaMantra now. The following Cite from "Shree Naradiya-Kalpa" is utterly peachy:
"Bhagavan Narada has declared in Srimad Ashtakshara Brahma Vidya that there are, in different men, varying degrees of faith in the Moolamantra. (He says):
“In proportion to the degree of faith that a man has in Ashtakshara, will he attain the fruit thereof. It is impossible to measure The Greatness of Shree MoolaMantra now".
