We want to distribute our literature and books within as well as our prasadam, and injecting our Hare Krishna medicine within the ear. So, reading of the literature and hearing of the chanting is the medicine, and prasadam is the diet. So, if diet and medicine are properly administered the disease of maya will be cured. But the physician must be always healthy. People may not say, physician is ill thyself. That means the preachers must be of highly elevated character, following strictly the rules and regulations and chanting regularly in the temple.
