*Mindfulness ('Insight') Meditation in itself has two Main purposes: the first is to develop mental concentration. The second is to gain ‘Insight’ into the nature of things through “mindfulness, awareness, vigilance and observation.” Mindfulness (Insight) Meditation is intended 'to purify the mind'. It cleanses the thought process of what can be called psychic irritants, things like greed, anger, ignorance, depression, anxiety, impatience,and stress - things that keep us snarled up in emotional bondage. 'It brings the mind to a state of tranquility and awareness, to a state of concentration and insight'. When one practices mindfulness meditation, he meditates on anicca (impermanence), dukkha (suffering), and anatta (non-self), using the breath as an anchor. The key to mindfulness meditation is observation without attachment. Basic Mindfulness (Insight) Meditation: Find a quiet and comfortable place. Sit in a chair or on a cushion on the floor with your head, neck and back straight but not stiff. Put aside all thoughts of the past and the future and stay in the present moment. Become aware of your breathing, focusing on the sensation of air moving in and out of your body as you breathe. Feel your belly rise and fall, the air enter your nostrils and leave your mouth. Pay attention to the way each breath changes and is different. ‘Observation-without attachment-is an important key to mindfulness meditation’. In mindfulness meditation one is 'an observer' of thoughts that arise in the mind during meditation. These thoughts are not harshly judged but are recognized as they simply are: thoughts and feelings. They are not to be clinged (attached) to, for clinging (attachment) causes suffering. We use the breath as an anchor. What does this mean? When a thought/feeling arises in the mind, we observe it-making a mental note of it, then gently return to the breath. If you’re observing your thoughts and emotions without getting caught up in them, then your on the right track. Remember not to be hard on yourself when your thoughts wander; be gentle with the mind, and simply return to the breath.
Jon Kabat-Zinn Ph.D. is alright when it comes to teaching mindfulness meditation. But I would highly suggest Henepola Gunaratana and Andrew Weiss, as insight teachers. *Learned Mindfulness Meditation from their books: '"Mindfulness in Plain English" - By: Henepola Gunaratana. It's a how to manuel on the practice of Mindfulness Meditation -covering how to meditate, what to do with your body, what to do with your mind, dealing with distractions during meditation, what the difference is between Sati (mindfulness) and concentration, the practice of Loving-kindness Meditation and Mindfulness in Everyday Life.*"Beginning Mindfulness: Learning The Way of Awareness" By: Andrew Weiss - which teaches Mindfulness of Breathing, Walking Meditation, Mindfulness Meditation, and Mindfulness in Everyday Life.
