Not only a truer knowledge, but a greater power comes to one in the quietude and silence of a mind that, instead of bubbling on the surface, can go to its own depths and listen.
In silence a question has great power, because in silence a question will always lead you deeper into your experience. If there is no grounding in silence, a spiritual question is going to lead you into your mind.
My friend, I am not what I seem. Seeming is but a garment I wear — a care-woven garment that protects me from thy questionings and thee from my negligence. The "I" in me, my friend, dwells in the house of silence, and therein it shall remain for ever more, unperceived, unapproachable.
The pause - that impressive silence, that eloquent silence, that geometrically progressive silence which often achieves a desired effect where no combination of words, howsoever felicitous, could accomplish it.
