Can you get behind the idea of a Holy Ghost?

I am not a Catholic, nor am I a Christian. I have explored DEEPLY into many religions, and I find truth and value in all of them. I DO, however, believe in "Christ", THE FATHER, and The Holy Ghost. The reason there is no "entity" to represent the Holy Ghost is because it would defile it's true nature. The Holy Ghost is a great mystery and cannot be fully understood. The Holy Ghost is not a being, nor is it a single, tangible existence. The Holy Ghost can, however, be experienced. The Holy Ghost has very little to do with physical creation, whereas Christ and THE FATHER do. The Holy Ghost, or Holy Spirit is in the essence of our souls and our TRUE being. In death, you will come to know and understand the Holy Spirit, because you will be existing within it. I hope this helps.
