Temperance

Upright

moderation · blending · practice

Two things that should not work are being combined with skill and slowness. The result depends on proportion, not intensity.

Reversed

excess · impatience · mismatch

Too much of one ingredient, or the mixture being rushed before it has had time to take.

Why this astrology

The trumps were attributed one by one to a planet, a sign or an element, which is how Temperance came to carry sagittarius · the careful mixture. Read it as that force arriving in the question.
