“Awareness cannot be practiced. There has been some confusion between awareness and mindfulness. They are related, but distinct. Sati, or mindfulness, implies there is action of the mind. We purposely set ourselves to pay attention to our minds. We exert effort. Awareness is different. Awareness is devoid of any action. The mind simply "awares." There is no action here, only a collected and spontaneous awareness that just "sees." Here, mindfulness is the cause, and awareness is the effect. You cannot practice or train the effect. You can only practice something that will cause it. We have to start with mindfulness so that awareness may arise in us.
