The Hanged Man

Upright

pause · reversal of view · surrender

Nothing moves, and that is the instruction. Hanging in place turns the picture upside down until the thing you were missing becomes obvious.

Reversed

stagnation · martyrdom · pointless waiting

Waiting that has stopped teaching anything, or a sacrifice being made mostly so it can be seen.

Why this astrology

The trumps were attributed one by one to a planet, a sign or an element, which is how The Hanged Man came to carry water · suspension that changes the view. Read it as that force arriving in the question.
