“Seth material” search engine (Jane Roberts)

Since any materialization is in effect a mediation between what we may call an ideal which is, by nature, of itself not materialized, and a practical working perceivable symbol of the ideal, each materialization must be composed of some camouflage elements. Within the physical field these perceivable symbols are composed of matter, which is a conglomeration of atoms and molecules. Each individual, creating, say, his version of any given chair, uses entirely different atoms and molecules in his subconscious construction of it.

He sees or perceives only his own construction. A rereading of sessions dealing with the nature of matter will help you here. The chair created then by any given individual, and perceived by him, is an identity in that it exists at any given time, without any exact duplication. Basically, for any duplication to appear, the exact atoms and molecules would have to be used, and this is obviously impossible.

The chair is an identity, and yet at no given moment is it the same chair, for already the atoms and molecules that compose it have changed, and been replaced by others. This process is explained thoroughly also in the mentioned previous sessions.
