The Guilt card, Emotions family, yin polarity, evokes a heaviness born of a gesture judged ill-fitted. It doesn't call for punishment, but for possible repair, when that's still useful. This card invites you to distinguish real responsibility from the extra weight you place on yourself.
In Oradia's mirror-card system, Guilt answers to Pride: the two don't oppose each other, they answer each other, like two sides of the same movement.
This page gives the card's general meaning. In a real draw, the Guilt card is always read in relation to the other cards drawn and the intention set at the start — it's that combined reading, unique to each draw, that the online oracle develops.
