Allāh ﷻ asks the servant to witness Truth. To hear, see and understand Eternal Truth. Openings come to those who ask and they are awarded according to their levels. The heart must be in a wholly giving position. These realities are not learned from books. Holy guides have the keys to such learning and with angels to assist, help weak servants reach heavenly understanding. The physical being is unimportant but the understanding capacity spans the universe.
