The Listen card, Actions family, yin polarity, evokes an ear leaning in toward a murmur. It signals the usefulness of receiving before responding. This card invites you to let the other person, or the situation, speak a little longer.
In Oradia's mirror-card system, Listen answers to Act: 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 Listen 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.
