Regarding the initial progression from M.T. to Magus, I've always liked this image:

The particular was raised to and permanently absorbed into Nuit upon crossing the abyss to become the homogeneous waters of the great sea of Binah. After being fermented in this state for however long there forms a seed in the darkness. The infinite now distills back into awareness akin to the all-seeing eye where there is no individual creating obfuscation. This liberates a great boon of life energy akin to the Chiah soul of Chokmah. The beginning stage of the Magus is akin to Mercurius birthing from the great sea as above, a baby's gnosis per Hoor-paar-kraat, the buddha, etc.
The main process as I see it is the distillation of the those universal waters into an enlightened Buddha drop as it were, where one is now fully awakened in contrast to when one was below the abyss and separated from the continuity of Nuit.
