Basic Tarot Meaning – “At #0 (or, in some decks #22) the Fool is the card of infinite possibilities and the beginning of a new journey. As much the keyhole in a door about to be opened as the first energetic step through the doorway itself.
But the card carries a little bark of warning as well. While it’s wonderful to be excited about what lies behind the door and excited by all the potential, you still need to watch your step. It is important to remember caution when you are unsure what lies on the other side of a door, lest you fall and end up looking the fool.”
