Meditation is a way of contacting the inner energy that powers the natural processes of healing and self-realization. Many cultures preserve some form of ritualistic technique - in one or two cultures dating from thousands of years ago - that promotes change from the normal levels of perception and that may result in feelings of well-being. This is probably why meditation in one form or another is central to the practice of so many of the world's religions.The word meditation comes from the Latin meditatio, which originally indicated every type of physical or intellectual exercise, then later evolved into the more specific meaning "contemplation."Eastern spiritual teachings, including meditation, have been adapted and increasingly practiced in Western culture.The use of Meditation for healing is not new. Meditative techniques are the product of diverse cultures and peoples around the world. It has been rooted in the traditions of the world's great religions. In fact, practically all religious groups practice meditation in one form or another. The value of Meditation to alleviate suffering and promote healing has been known and practiced for thousands of years.Whereas some traditions are strictly mystical, directed toward a unity with all creation and an infusion with sublime joy, others may be described as more pragmatic, striving instead toward what is simply a state of "being" that includes no aspect of movement or sensation. For some people, especially in the Christian faith, prayer is a form of meditation. What is always involved is time out from the world around and a stilling of the mind.Although it is possible to learn meditation techniques from a book, it is much better to have a teacher. Failing this, a tape can be helpful. It is usual to start by adopting a comfortable posture in a quiet location and closing your eyes. At first it may be difficult to steer the attention gently away from your racing thoughts without forcing the mind to behave in a set way. The vocal repetition of sounds (a mantra), or a visual object of devotional significance to which the attention may be recalled when necessary, is helpful to some people.It has been found that meditating effects changel heart rate and respiration, helping to reduce stress. As the thoughts slow and the level of tension in the body drops accordingly, feelings of calm, detachment, peace, and sometime joy begin to fill the mind and spread through the body. Meditation promotes a state of deep relaxation, but also mental alertness and openness. An equilibrium between activity in the rational left side of the brain and the creative right side of the brain is established and there is an overall increase in the brain's range of operation.
