From my point of view, the image of Christ symbolises the ‘crossing’ event
Please notice how the ‘cross’ is incomplete.
Just White light. Symbolising the source of all matter and creation. The great secret is revealed; polarity, alpha & omega arose from the same beginning. Life has not ‘happened’, it’s ‘happening’ and that’s what is being experienced, Now.
This further underpins the lore that Jesus desired everyone to become living Christ’s, not cross-carrying Christians.
