ANSWER: There are many techniques from different traditions and teachings, but all of them usually involve some combination of energy, words, and images. The words and images express your intent, and the energy gives power to your intent. The fundamental assumption behind all of this is that good thoughts can support good causes over great distances, just like prayer. So here is a basic process that anyone can use:
1. Take one very deep breath;
2. Say what you want (ex: "Let there be the right amount of rain needed in Texas");
3. See what you want (ex: rain clouds moving over Texas and releasing the right amount of rain);
4. Take another deep breath to finish.
