(6.16) The power of the individual to think is his ability to act upon the Universal and bring it into existence.
(6.6) This may be changed through the process called thinking. Thought creates brain cells and these cells respond to the corresponding thought in the Universal.
Not all vibrations are equal in creative potential. We act upon the Universal by thinking, and thought creates vibrations. We changed these vibrations by directing our attention toward other thoughts.
