Quote from : Letters of the Scattered Brotherhood Book

Your past experiences are past indeed; those strains and emotions of sensuous life are gone and what has remained is the temple of your own building, that edifice not built by hands. The reality of you is in the invisible, the intangible. In retrospect your spiritual milestones stand stronger to you in their fixed position than any outward experience. Having arrived at this understanding try now, quietly, gently, without too much effort of self-discipline, to keep to the invisible, train yourself to keep immaterial. Watching and praying are essential. When hard pressed by old habits and you are under the heavy blanketings of times and events, you, as it were, disappear. This is the moment to step back into the invisible, for then the invisible will enfold you and give you great power in the visible world.
