Since we have the power to choose our experience, we also need to accept responsibility for this. Perhaps not that everything that comes our way is a direct result of our own thinking (though some might say it is) but what we attract into our life is, largely, a reflection of our thinking. Much of this occurs on a subconscious level, but the subconscious takes its lead from the thinking mind, so changing our thoughts will change our world, and we are responsible for this.
Our behavior is a natural outcome of our mental images, and so we are responsible for our behavior too, and also for the behavior we tolerate in others. If we allow others to ride roughshod over us, then we have ourselves to blame.
