Is Knight of Cups a yes or a no?

This card leans yes. It carries forward movement, and in a straight yes/no draw most readers take it affirmatively.

The Knight of Cups is the romantic, following feeling wherever it goes, at a walking pace. Charming and sincere, and not always reliable, because feeling is what he steers by and feeling changes.

He is the only knight not in a hurry. The horse walks, the cup is held out rather than carried, and the winged helmet and heels are Hermes: a messenger arriving with something rather than a soldier going somewhere.

The tradition's honest note about him is that sincerity and dependability are different qualities, and this card has the first without any guarantee of the second.

Yes/no readings are the most popular use of tarot and the one it is worst suited to. A seventy-eight card deck built to describe nuance is being asked for one bit of information, and most of what it knows is discarded in the process.

A more useful version of the same draw: read Knight of Cups as what shape this takes, not whether it happens. An offer made from the heart. Romance, an invitation, a creative proposal.

Follow what moves you. Grace and idealism in action, and the card genuinely means action: the Knight is moving, which distinguishes him from the Page's feeling that has not gone anywhere yet.

As a person he is warm, attentive and demonstrative. What he offers is real at the moment he offers it, and the tradition is careful to put it that way rather than more warmly.

Reversed, the lean weakens or inverts. Moodiness, unrealistic promises, somebody in love with being in love.

The last is the most precise. What is being enjoyed is the feeling rather than the person, and the person is interchangeable in a way that becomes apparent later.

Also read for feeling that never becomes action: the intention announced repeatedly and never enacted. Reversed, the horse stops and only the declaration remains.
