Spiritual attainment is not a thing to be brought before people to prove that it is real, or as a show. What is real is proof in itself, what is beyond all price or value does not need to be made much of before people. What is real is real, and the precious is precious in itself: it needs no explanation, nor pleading.
The greatest lesson of mysticism is to know all, gain all, attain all things and be silent. The more the disciple gains, the more humble he becomes, and when any person makes this gain a means of proving himself in any way superior to others, it is a proof that he does not really possess it. He may have a spark within himself, but the torch is not yet lighted. There is a saying among the Hindus that the tree that bears much fruit bows low.
