This spirit is the discovering power that encompasses all things. All the wondrous signs, all the crafts and discoveries, all the mighty undertakings and momentous historical events of which you are aware, have been discovered by this spirit and brought forth from the invisible realm into the visible plane through its spiritual power. Thus it abides upon the earth and yet makes discoveries in the heavens, and deduces that which is unknown from known and visible realities. For example, man is in this hemisphere, but through the power of reason he discovers, as Columbus did, another one- the Americas- which until then was unknown. His body is heavy, but he flies through the air by means of vehicles of his own devising. His movement is slow, but he journeys rapidly through East and West by the aid of the devices which he has fashioned. In short, this power encompasses all things (36:4)
