You have to grow from the inside out. None can teach you, none can make you spiritual. There is no other teacher but your own soul.
I find distasteful the traditional idea of Christianity which preaches the resurrection of the body. Frankly, I see my body as more of a limitation than a virtue, and I will be glad to be free of it rather than having to continue to cart it around. I prefer to believe that souls can exist independently from bodies.
