Every thought, word (written, spoken externally and internally) gains power as we move through the scale of emotion. This is part of the universal fail safe. Evolution occurs as we master our emotion by transmuting anything less than love, within our own consciousness.
As we become more consciously aware, responsibility increases.
Power is directly related to the influence we project into physical reality.
Contemplate that in terms of what we call prayer. Evolution of consciousness is dependent on mastering (through transmutation) the emotional body.
