On a slightly higher level, you cannot rid yourself of an ego you do not have.
Christians are notorious for splitting the soul and body in unhelpful ways, but I think if one thinks of “the body” as the feelings I am sensing and releasing, that it is very much something that should be rejected.
But it has to be done from a position of wisdom. All our instincts exist for reasons, it is the PERVERSION of instincts–turning the alarm system into a state of permanent fear, for example, which is sounding all the time and thus useless; or turning the joys of the sexual instinct into lusts for power and purely physical experience–which is to be rejected.
I do sometimes feel an energy like that called the Devil does exist. I feel a spirit trapped in this world, not the ruler of it, trapped because it can neither grow nor diminish. It is stuck like a monkey in a monkey trap of the sort where something desirable is placed at the bottom of a bottle tied with a string. It can place an open hand in, but it cannot pull the thing out without opening its hand again, thus releasing the treat.
This something still speaks to us through the primordial muck from which we arose as spirits. We can heed it, or we can let it go.
