A note dating from 1670, is in the pseudo cryptographic language of alchemy and is signed Jehovah Sanctus Unus, the name Isaac Newton used on his mystical writing.
“The “seals,” which are impressed on the soul, protect it against the flood and guarantee its normal functioning. Why is the soul, as it were, sealed up? Because, answers Abulafia, the ordinary day-to-day life of human beings, their perception of the sensible world, seeds and impregnates the mind with a multitude of sensible forms or images (called, in the language of mediaeval philosophers, “natural forms”). As the mind perceives all kinds of gross natural objects and admits their images into its consciousness, it creates for itself, out of this natural function, a certain mode of existence which bears the stamp of ϧniteness*. The normal life of the soul, in other words, is kept within the limits determined by our sensory perceptions and emotions, and as long as it is full of these, it finds it extremely difficult to perceive the existence of spiritual forms and things divine. The problem, therefore, is to and a way of helping the soul to perceive more than the forms of nature, without its becoming blinded and overwhelmed by the divine light, and the solution is suggested by the old adage “whoever is full of himself has no room for God.” All that which occupies the natural self of man must either be made to disappear or must be transformed in such a way as to render it transparent for the inner spiritual reality, whose contours will then become perceptible through the customary shell of natural things."
