Caitanya Caritamrita, Madhya-lila 17. 133
nama cintamanih krishnas
purnah suddho nitya-mukto
namah—the holy name; cintamanih—transcendentally blissful giver of all spiritual benedictions; krishnah—not different from Krishna; caitanya-rasa-vigrahah—the form of all transcendental mellows; purnah—complete; suddhah—pure, without material contamination; nitya—eternal; muktah—liberated; abhinnatvat—due to not being different; nama—of the holy name; naminoh—and of the person who has the name.
“‘The holy name of Krishna is transcendentally blissful. It bestows all spiritual benedictions, for it is Krishna Himself, the reservoir of all pleasure. Krishna’s name is complete, and it is the form of all transcendental mellows. It is not a material name under any condition, and it is no less powerful than Krishna Himself. Since Krishna’s name is not contaminated by the material qualities, there is no question of its being involved with maya. Krishna’s name is always liberated and spiritual; it is never conditioned by the laws of material nature. This is because the name of Krishna and Krishna Himself are identical.’
This is a quotation from the Padma Purana.
