This is a famous phrase used by the British television comedy sketch group Monty Python in the 1970s. It was used to introduce something that was possibly bizarre, and had no relation to the previous segment. ACIM sometimes speaks of possible “future” states that seem quite bizarre and have no relation to the current world and its science as we know it. Look at this phrase from ACIM, "[The Real World] is not lit with artificial light, and night comes not upon it. There is no day that brightens and grows dim." (OrEd.Tx.12.59) This is not talking about Heaven or Reality, but the healed world, the last step before Heaven. Yet how could this be? Perhaps this teaching from A Course of Love gives us a clue, "This is a harmony and cooperation that might one day extend to the sun and a demonstration that the sun need not rise – or perhaps need not set – and the earth would still be safely spinning in its orbit." (D:6.12) I call on everyone to let go of what seems scientific and possible, and to prepare for something completely different – something truly miraculous.
