Prabhupad's Explanation for a question, asked by a devotee ,about "Responsibilities of a Guru"
SYAMASUNDARA: One time you said that sometimes you feel sickness or pain due to the sinful activities of your devotees. Can sometimes disease be due to that? Caused by that?
SRlLA PRABHUPAI: You see, Krsna says:
aham tvam sarva-papebhyo
moksayisyami ma sucah
"I will deliver you from all sinful reaction. Do not fear." So Krsna is so powerful that He can immediately take up all the sins of others and immediately make them right. But when a living entity plays the part on behalf of Krsna, he also takes the responsibility for the sinful activities of his
devotees. Therefore to become a guru is not an easy task. You see? He has to take all the poisons and absorb them. So sometimes- because he is not Krsna-sometimes there is some trouble. Therefore Caitanya Mahaprabhu has forbidden, "Don't make many Sisyas, many disciples." But for
preaching work we have to accept many disciples-for expanding preaching-even if we suffer. That's a fact. The spiritual master has to take the responsibility for all the sinful activities of his disciples. Therefore to make many disciples is a risky job unless one is able to assimilate all the sins.
As a devotee We should be very much cautious: "For my sinful actions my spiritual master will suffer, so I'll not commit even a pinch of sinful activities." That is the duty of the disciple.
