What is true spirit?

I have a yearning. To become spirit. To shed my body. My physical being. Yet still be alive. Aware. I imagine spirit as a conscious existence. But without the handicap of being locked up. Inside something. Contained. I want to be free. To go anywhere in all of creation.  To live on the same plateau as the creator. In a sense, to be his equal. Unencumbered by the physical realities of life. Able to observe the physical. Without being in it.  I wonder if true spirit exists. Now. Inside me. Is it the soul? I am enamored. By the thought of spirit. Wondering. Wondering. What is true spirit? –Jim Broede
