What is the First Dimension? The first dimension exists as a single point at the center of the earth. If this switch is open 0, we feel we are grounded to the earth; that is, belong to the earth. If this switch is closed 1, we regard the center of the earth as merely a place existing somewhere below us. Root Motivation The first dimension is the Root Motivation or originating root of the personality in activity. This would be at the most fundamental level as an extrovert (outer activity) or introvert (inner activity). (c) Copyright Jonn Lavinnder, 2007. All rights reserved.
