There is no point in lamenting the world. There is no point in taking action to change the world. It is incapable of change in and of itself because it is entirely an effect. The only change we can effect is a change of our thoughts about the world. Every thought we have makes up some part of the world we perceive. Only by changing our thinking do we change the cause. The effect will change as a result automatically. To change our perception of the world then, it is exclusively with our own thoughts that we must work.
