One of the effects of chanting is that we become peaceful, free of anxiety. A person may thus chant in order to become peaceful in the fulfillment of his sense gratification. His goals are all material. Such a person can never achieve love of God and will never attain suddha-nama. It is only by some great fortune—either by receiving the mercy of a powerful Vaishnava or of the Lord Himself—that we can come to the platform of pure chanting. One who does not even wish to attain pure chanting will never be able to attain it.
