From Llewellyn’s Sabbat Essentials book on Mabon

You’ve heard the adage “as you sew now shall you reap”. This is a way to look at what energy you have put down and where it will lead, and what you will have to work with when your path has led in its own direction. 

This spread requires 24 cards total in three groups of eight: 

• The first eight cards represent your more distant past, things sewn long ago. 
• The second eight cards refer to your immediate past and present.
• The last eight cards refer to your distant future.

In each group of 8, the first 4 cards represent what you have sown. The next four cards in that group are what you will reap because of the action referred to in the cards above it. Shuffle the cards and repeat the whole process two more times so you have three sets of cards to interpret.

Some cards hold special weight:

Justice is about having what is lost restored to you. Judgment is about the necessity of responsible actions. Often when one shows up in a reading the other follows shortly after. 

If Temperance appears near these cards, it is a signal that what has happened is a direct consequence of your own choices. 

If the Magician appears, you have the power to change it. If the Hierophant appears, it is time to seek higher wisdom.
