Various Forms
Mindfulness is an open form of practice in which the practitioner focuses attention on a process or object . While practicing mindfulness our focus is in the present moment. Through mindfulness we begin to see how uncontrolled our mind is. We begin noticing the constant chatter of the internal dialog. Through mindfulness we observe the nature of thoughts and begin to witness them without judgment. Noticing the incessant commentator is the first step in improving the way our mind works and freeing yourself from judgments and preconceived perceptions allowing for a more “real” look at the world.
Concentrative is a more closed form of practice. The practitioner trains the mind to focus on a single object, minimizing distractions, always returning the mind to the focal point.
