“My body is a wholly neutral thing.”
Your body is a neutral thing. Unfortunately, the body is not usually viewed as such. It has become invested with a misplaced sense of identity. Through that investment it has become more to you than a physical shell.
Your identity is not the body; you are creative thought, vibrantly alive. The body is a neutral thing, and can be used very effectively by the Holy Spirit when it is offered up.
Trouble arises when identification happens, for identification pulls you away from creative thought down into the square millimeter of form, and your Spirit cannot soar.
