The student is mistaken if he thinks the teacher ever places obstacles or temptations in anyone's way. He does not have to do that; it is done by life itself, or, more precisely, by the karma arising from the individual character and its special needs. The teacher may note them and act accordingly, but he does not create them. In the end, the student himself creates his own obstacles and his own temptations by his thinking, by his character, and by his karma.
