Conceptions of God in monotheist, pantheist, and panentheist religions – or of the supreme deity in henotheistic religions – can extend to various levels of abstraction: as a powerful, personal, supernatural being, or as the deification of an esoteric, mystical or philosophical entity or category; as the "Ultimate", the summum bonum, the "Absolute Infinite", the "Transcendent", or Existence or Being itself; as the ground of being, the monistic substrate, that which we cannot understand; and so on.
