The personal present subconscious could be compared, using this analogy, with the topmost layer of soil dealing with the present seasons. Through it reach the roots of living emotions and desires. Directly beneath, still using our analogy, will be found the nutrients and seeds of those desires. The topmost layers of the subconscious hold then, first of all, almost conscious just-under-the-surface needs and desires; and under these those more deeply buried, reaching backward to birth, even as the loose dry autumn leaves still contain traces of earlier pigment.

It is from this layer that so-called secondary personalities may sometimes arise, usually due to one of the psychic earthquakes mentioned earlier. As earthquakes cause lava to boil up seemingly from the center of the earth, so do some secondary personalities in their explosive emersion bring with them debris from other levels of the subconscious, often personifying themselves in the guise of those buried and frightening fears that have, until then, found no vehicle for expression.

It is also possible that these secondary personalities, emerging, give access to buried abilities and benign constructive abilities which had been buried beneath heavier fears that weighed them down. In any case this level represents the last division of what we may call the present personal subconscious, and still only accounts for a small dimension of the inner self, being composed of only the most easily accessible portions.

This phenomena is more common however than you would suppose, though unfortunately in many cases the secondary personality gives personification to buried fears and fantasies that are unhealthy to the dominant personality. Not only this, but because they are released by a psychic earthquake they emerge forcibly and sometimes with more vigor than the present personality can handle, so that they are in a position to dictate terms to the dominant personality.
