The mind itself is a potent instrument for change, the only one there is.
All change must take place in the mind first,
for all action is a result of thought and the resultant impulse or motivation.
You are the One Self whether you are aware of It or not.
Your mind functions by means of a Light that comes from beyond it.
The Light of the Self pervades the body-mind of separation; without this Light, there would be no mind.
You cannot use this Light of Mind creatively however, for the body-mind reduces this creative power of the universe to partial perception, conceptualization which it regards as thinking, and habit patterns of thought and feeling.
It is as if you took the power produced by a huge dynamo and used it to run a toy train.
Very little of the power potentially available to you is actually used in your life.
Even that is misused to make sure this greatly reduced mode of functioning is maintained.
The Light within you is brighter than a thousand suns, brighter by far.
