The Fool is the first card in the Major Aracana.
It has the number 0, for someone ready to go in any direction, open to all possibilities.
In the Advice position, the Fool advises that you lighten up. Let yourself be spontaneous enough to stretch beyond the realm of logic.
There is no advantage to be gained by thinking you possess the knowledge, power, or control to direct reality.
Open and receive without question, instead of trying to manage what's happening right now. The Fool has no ambition to manipulate a specific outcome.
