There are, of course, certain things that the disciple is told to do during his training, and certain spiritual practices are given, which are different for each one. The disciple during his training does not make use of any knowledge or any powers that he acquires. That would be as if every medical student, as soon as he entered the medical college, were to prescribe for patients. It would be terrible. He would kill everybody. Sometimes they become impatient and use their powers before the right time, and the results are very bad.
