The Liberation card, Transmutation family, yang polarity, evokes a dam giving way, letting life flow again. It signals the end of a constraint that had been weighing on you for a while. This card invites you to notice what becomes possible again once the obstacle lifts.
In Oradia's mirror-card system, Liberation answers to Letting Go: 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 Liberation 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.
