While the aspirant is still unbalanced in personality, undeveloped in capacity, and uninformed in attitude, his psychical "experiences" are not likely to be of much real value or importance. Yet, precisely because of this immaturity of his, he will exaggerate their value and magnify their importance. One consequence of this is that they may not only obstruct but even harm his progress if he dwells on them. Hence a competent teacher will discourage most talk about them. He wants to hear that the aspirant has begun to overcome an unworthy impulse, not that he has "seen" some mystical vision.
