“In bringing about this inner spiritual transformation of consciousness, the sādhaka has to progressively sharpen or refine his perceptive faculty so that he can perceive increasingly deeper significance in the content of his mind without changing the nature of that content. It is this sharpening or refining process which, when carried to the extreme limit, enables him to perceive the Ultimate Reality that pervades and contains the manifested universe but remains unknown for lack of perception. “
