The materialist thinks that persons engaged in Krishna consciousness are crazy fellows wasting time by chanting Hare Krishna, but actually he does not know that he himself is in the darkest region of craziness because of accepting his body as permanent.
After searching through all the Vedic literature, one cannot find a method of religion more sublime for this age than the chanting of Hare Krishna.
Chanting Krishna's sweet name purifies the heart, sanctifies and steadies the mind, destroys the six enemies [lust, anger, greed, envy, illusion, madness], stops birth and death, dissolves sins, scorches samskaras, annihilates attachment, induces detachment, uproots desires, empowers one, makes one fearless, removes illusion, bestows supreme peace, delivers prema, reveals the Lord and His dhama, shows one's svarupa, showers bhakti-rasa and engages one in his nitya seva for the pleasure of Radha Shyama.
There is distinction even in wood. There are so many jungle woods, we can use it for cooking. However, the sandalwood, which is so valuable, if we do not know what is the value of sandalwood, if we use it for cooking and burning …. Similarly, if we use this human form of life exactly like the cats and dogs, simply for sense gratification, then we are committing suicide.
