Shifting External Reality is a practice that can alter your sense of self perception.
A huge revelation is that anything we perceive in others and the outside world are actually part of ourselves. This means whatever we admire or despise, whatever excites us and evokes discomfort, is all part of a positive or negative shadow.
Taking personal responsibility for our perception implies a willingness to be accountable. In essence, we realize, we have no one to blame but ourselves. It means we determine our behavior and how we see the world.
From the moment it hits that we are the source of all our perception, we can grow into a conscious agent of change. To do so requires we be willing to recognize that so long as we project into the external world, we cannot completely embody our creative gifts.
