It is common for people to talk to themselves or hear seemingly external voices to a certain extent. Thankfully most of us do not have to go through what Eleanor Longden did.
I wonder if she still hears voices? At the end of the talk she says “What lies within us can never be truly colonized …” I’m not exactly sure what she means by this but I see the objective of personal development as colonizing our own bodies as fully as possible.
In order to assist people in more fully inhabiting their own bodies it is necessary to displace any other entities that may have taken up residence there. To do this I have developed a way of facilitating re-connection (facing towards the source of the voice), de-fusing (taking back what is yours and giving back what is theirs), and separation. I find that there is rarely (never?) any need for cutting.
Eleanor talks about her voices being companionable. One of the consequences of separating from entities is that people often have to experience their own feelings of emptiness or loneliness. This would be the next thing to work through in therapy.
When this process is successful I would expect clients to find that the voice has completely gone, that they feel more fulfilled, and they are more able to bring their full attention to the world around them.
