After the Spell is Over

When the work is finished, if the goal is something you can work for on the physical as well as spiritual planes, so so immediately in order to help your spell take effect. 

If you were casting a spell for a job new apartment, for example, get onto Craigslist. 

If, on the other hand, the matter is one in which your only control is magical (a far healing, for example), it is best to let go of the spell and refrain from thinking about it for awhile, giving it time to take effect.

If the spell involved a concrete magical image like a picture or a poppet, that should be kept on your altar or in some other safe place until the need for it has passed. 

In some cases, the image is a talisman which is given as a present to the person for whom the spell was cast. 

If you eventually want to dispose of a magical image or talisman, it can be burned, buried, or thrown into water. Take pains to avoid littering.

In some cases, you may want to deactivate an image or talisman by cleansing it with one or more of the elements, and then use it for another purpose. A poppet, for example, can be packed away in rock salt and rosemary for a time, and then used to represent another person in another spell. 

Similarly, a crystal can be washed with salt water and then charged again for another purpose.

I find that in spite of all I can do, the regular habit of spell-casting inevitably results in an accumulation of ritual rubbish. 

Ultimately, when something has been lying around so long that you no longer remember what it was for, it is safe to assume that its magical charge has worn off and that it can just be deposited in the trash.
