A Walk Through the Thoth Tarot
Ten of Cups
Crowley, in a letter to Lady Harris says, "the background out to look menacing. There is something sinister about this card - it ought to suggest a morbid hunger which springs from surfeit." In other words - perhaps too much goodness - so much so that the cups can't even hold them and it's just all spilling on the floor. Crowley blames Mars (which is in Pisces for this card) He says, "Mars is the gross, violent and disruptive force which inevitably attacks every supposed perfection."
So, the generic meaning is: Mattered settled: complete good fortune. Permanent and lasting success and happiness - because inspired from above.
Which is a good thing - this card tells us things are in their proper places and that we are finally in harmony with the Universe. I think Crowley's warning up there tells us not to take this for granted. Also to stay mindful of what is happening in the Now - stay in the moment and don't get ahead of yourself.
