Wheel of Fortune: tarot meaning, upright and reversed

A wheel turns among ascending and descending figures while four winged beings attend the corners.
Upright
turning point · cycles
Conditions are changing. Notice the opportunity and the limits of personal control within the cycle.
Reversed
resistance · instability
A turn of events may unsettle expectations; repeating a familiar response can prolong the difficulty.
In a reading
The position gives this card a particular task: a description of the situation, a challenge, or guidance. Read its image and meaning alongside the other cards and the question that brought them together.
