Manifestation is a process used to create or allow circumstances, effects or material to exist. The beginning step is a conscious decision and absolute conviction to allow that which you have realized that you truly desire to be real. It cannot start until you know exactly what it is you really want. Vague ideas produce vague results, if any.
Once you determine and define that which you strongly desire, be it fame, fortune, love, inner peace or anything else, Manifestation can begin. You must be able to concentrate on what you desire, though, not the lack of it. To spend time wishing for something that is not there puts all your energy into creating more of its absence. Proper training into where to direct your thought energy is necessary for most people. Fortunately the material has already been gathered for you, for to search through centuries of writings of Manifestation Masters would take up a large part of your lifetime.
You must learn to concentrate in the very present moment, without distraction or resistance. Your thoughts must not be watered down with imagined worries or fears of what may or may not happen. To gather all of your energy together and imagine the worst case scenario of the existence you truly do not desire gives it a life of its own and you may well manifest this instead of what you do want.
The contemplation of what does not exist right now is why you begin your practice of manifestation, so this immensely powerful process must be trained on the correct targets. According to Quantum Physics, nothing ever can be created or destroyed, so therefore everything must already exist. You must learn truthful and accurate ways to manifest the proper outcome, or destroy your life in the process. Many people with enormous perceived potential spend their lives wandering aimlessly, because they concentrate on the lack of prosperity instead of the unfailing lavish abundance that already exists throughout the universe, and is available to anyone with the access to the keys.
When your thought energy is channeled along the right vectors, nothing that you can imagine cannot be created by you. All you have ever dreamed of is waiting for you choose, and manifest into existence for yourself. Manifestation is an omnipotent force that cannot be reckoned with, once set into motion. Learn the absolute reality of manifestation, and all you crave is yours to accept.
