Your beliefs, thoughts, and emotions create your reality. Thoughts are made of the same substance as matter, only the intensity is usually less with thoughts.
When you create a vivid image or thoughtform, you instantaneously create prematter on a deeper level where creation takes place.
If you imbue your thoughtforms with strong emotion you add intensity to them. This adds power to prematter events and increases the probability that they will manifest in their full purity. Emotions always speed up the manifestation of what they are attached to.
The laws are simple. Beliefs, thoughts and emotions lead to manifestation of objects, events and circumstances. Learn the principles to apply them correctly.
Once you understand how it is done, manifesting money is easy to do.
