Here’s a fundamental instruction in performing any act of magick:

1. Decide what you want to occur.
2. Ensure that what you want to occur has a means of manifestation.
3. Choose an experience.
4. Decide that the experience means the same thing as what you want to occur.
5. Perform the act / undergo the experience.
6. Result.
