“Seth material” search engine (Jane Roberts)

The beneficial or detrimental effect of the emergence of secondary personalities must and may be judged by its effect for good or bad on the dominant personality, for in your existence the dominant personality is necessary and must be maintained in an authoritative position, to deal with the physical world.

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.

From this focus position communication may be set up between personality essences no longer in the physical field, and those still in it, provided that those still in it are able to remove focus from the ego to this particular level. It is from this focus point then that communication between what is termed the living and the dead may take place.
