In the first case, it is not so much an entity, as a energy. In the second it is not so much bound to you as you are bound to it. It is not within you at all, however, it is connected to you.
For the first, I will mail you something on it shortly, for the second, I haven't connected with my higher self as of yet so I don't know how to tell you to. Lol.

i do believe i have contacted my 'higher self'. there seems to be a being that talks to me, in my mind. it tells me stuff & gives me advise. i talk to it as if im simply talking to someone else.
it started off when i just heard simple phrases and words, like "run" and "danger nearby", etc.
then i talked to it. it was mean & stubborn at first. but we got to know eachother, and now we talk freely. ^^
try meditate. then speak in your mind. see if someone/thing answers? hope it all works out. xoxo
