Jayapataka Swami:  Srila Prabhupada said that to make a devotee one gives buckets of blood. So as a doctor, you know how much blood we need!  By your prayers to Krsna, by your intense desire to help the conditioned doctors to become liberated and very patiently hearing them and answering all their questions, many of them should accept. There are four kinds of people that don’t accept. So if someone falls in that category, then it is very tough to make them devotees. maya apaharita gyana -someone whose intelligence has been stolen by maya – but even these tough nuts can be cracked, but it is not easy! Special mercy! Sometimes taking prasadam, sometimes reading books, sometimes special association, you don’t know what will reach these people. So people that are easily brought are of four types – those who are in difficulty, economic needs, inquisitive and wise.
