These words are taken from Italian Witchcraft by Raven Grimassi:
Every act which you perform will draw to itself three times the nature of the act. Such is the Law.
This effects not only the acts of each day, but reaches into the future as well. Here the Law establishes those debts which must be paid.
Therefore consider well your actions. Nothing escapes the Law, nor is anything hidden from it. The Law does not punish nor reward. It only returns the intent of each action to its origin.
If you step off from a high place you will fall, and this is consistent. There is no intent, there is nothing good or evil. It may be good to leap upon your enemy from a high place and surprise hime, or it may be bad to fall and be injured. But the nature of the descent it only a law. So too is the nature of the Law of Return.
