Attempting to manipulate and control the material world directly is counter-intuitive to the nature of how that world functions. Being that all matter is manifested from thought it would be instrumental for the real magician to focus attention and efforts upon the world of thought, as thought is where the material world can be manipulated before the act of manifestation itself. Doubt it not, this is the true nature of our world and those who understand this dynamic have targeted the core subconscious of the human race.
Even as these words manifest from within my mind through the keyboard and forever into the digital world which is incrementally tightening its embrace around us, you are being drawn further into the world I have created for us. Through the manipulation of letters and words, I am spelling out a magical spell which causes the transmutation of thought within each who reads the incantation. This is the truth which can be revealed and understood by those with the open mind of the mage and adept.
Matter is simple clay waiting for the direction of thought to form and mold its characteristics while devising its purpose. Weave the world from a billion minds. The more minds, the more manipulation of the material world which can be achieved. Overpopulation is a gift to the magician who truly understands this power.
