The purpose of Zazen Meditation is to free your mind of the materialistic hold our lives have on us and once you are able to allow your thoughts to enter and quietly leave without investigation you will no longer be limited. This will provide you the quiet calm needed to see the truth of your nature and your place within yourself and the world. Your body, mind, and breath will become one.
In layman's term, Zen meditation is letting go of pessimistic thoughts and simply relaxing. In Buddhism, it is a contemplative discipline performed to achieve calmness in the mind and body. Most importantly, it aims for a practitioner to understand the nature of life to obtain enlightenment. To fully experience positive results of Zen meditation, there are three general methods to consider such as Concentration; Koan Introspection; and Shikantaza.
