Every Visible Thing Is Only an Effect of the Invisible or Causal

Light is not only a physical element, it is also a mental and spiritual element and in the temple the disciple is told to revere the invisible sun even more than the visible one; for every visible thing is only an effect of the invisible or causal, and as God is the Cause of All Causes He dwells in the invisible World of Causation.
