Putting their feeling into words is the greatest pain for souls that live in the higher spheres. Subtle souls never say things that they should not say; it is not their desire to speak. The sympathetic mureed has to grasp, to feel what the teacher wishes to convey, what the teacher feels, how the teacher can be pleased, and what the teacher will be displeased with. And if the teacher has to descend to earth, so low as to have to tell it in words, then this means that there is no current. There is only a difference of two letters between worthiness and unworthiness.
