Potent (CC and Other Books)
Sri Caitanya-caritamrta
CC Adi-lila
CC Adi 1.59, Purport:
It is indicated that to learn the transcendental science, it is imperative that one avoid the company of undesirable persons and always seek the company of saints and sages who are able to impart lessons of transcendental knowledge. The potent words of such realized souls penetrate the heart, thereby eradicating all misgivings accumulated through years of undesirable association.
