One who takes the dust of a great personality's lotus feet transfers his sinful activities to that great personality. Unless the person whose dust is taken is very strong, he must suffer the sinful activities of the person who takes the dust. Therefore ordinarily it should not be allowed. Sometimes in big meetings people come to take the same advantage by touching our feet. On account of this, sometimes we have to suffer from some disease. As far as possible, no outsider should be allowed to touch one's feet to take dust from them. Sri Caitanya Mahaprabhu personally showed this by His example, as explained in the next verse.
