Central Self

The observer is the central self, the sense of identity, the “I” person. The attention or focus of the observer is channeled outward through the senses to hear touch, see, taste and smell. In the subtle buddhi organ there are individual orbs that correspond to each of these senses.
In this diagram which was drawn by Sir Paul Castagna, the attention of the self travels through the vision orb, where it is routed into the optic nerves to go through the eyes.
Of special note is the fact that the central self and its sense of identity are presented as the tiny light blue orb in the center. The buddhi organ is not represented even though it is in operation. The central self does not perceive it but only perceives the focusing attention energy flowing through the visual apparatus. This happens because the central self has limited perception and cannot always perceive the psychic adjuncts.

In this second diagram which was drawn by Mi~Beloved, based on Sir Paul’s original above, the observer, represented as a tiny light-green orb, is the central self with its sense of identity. The attention or focus of the observer is channeled outwards to the buddhi organ, which is represented as the oval white orb. From there the energy courses into the vision orb (in orange).
This takes into account the buddhi intellect organ which is usually invisible to the central self which has limited insight perception.
