Eintstein's definition of religion suits me. This is what he says religion is.
“A knowledge of the existence of something we cannot penetrate, of the manifestations of the profoundest reason and the most radiant beauty. It is this knowledge and this emotion that constitute the truly religious attitude. In this sense, and in this alone, I am a deeply religious man. I cannot conceive of a God who rewards and punishes his creatures, or has a will of the type of which we are conscious in ourselves. Enough for me, the mystery of the eternity of life and the inkling of the marvelous structure of reality, together with the single hearted endeavor to comprehend a portion, be it ever so tiny, of the reason that manifests itself in nature.”
