Meditation originated from Vedic Hinduism which is the oldest religion that professes meditation as a spiritual and religious practice. Evidence of the origins of meditation extends back to a time before recorded history. Archaeologists tell us the practice may have existed among the first Indian civilizations. Indian scriptures dating back 5000 years describe meditation techniques. From its ancient beginnings and over thousands of years, meditation has developed into a structured practice used today by millions of people worldwide of differing nationalities and religious beliefs.
Meditation is a discipline in which one attempts to get beyond the conditioned, "thinking" mind into a deeper state of relaxation or awareness. It often involves turning attention to a single point of reference. Meditation is recognized as a component of almost all religions, and has been practiced for over 5,000 years. It is also practiced outside religious traditions. Different meditative disciplines encompass a wide range of spiritual and/or psychophysical practices which can emphasize different goals - from the achievement of a higher state of consciousness, to greater focus, creativity or self-awareness, or just simply a more relaxed and peaceful frame of mind.

The mental ability to concentrate is inherent to all; it is not extraordinary or mysterious. Meditation is not something that a Yogi has to teach you; you already have the ability to shut out thoughts.
The only difference between this and meditation (the positive way), is that generally we have learned to focus the mind externally on objects. When the mind is fully concentrated, time passes unnoticed, as if it did not exist. When the mind is focused, there is no time! Time is nothing but a modification of the mind. Time, Space, and causation and all external experiences are mental creation.
All happiness achieved through the mind is temporary and fleeting; it is limited by nature. To achieve that state of lasting happiness and absolute peace, we must first know how to calm the mind, to concentrate and go beyond the mind. By turning the mind's concentration inward, upon the self, we can deepen that experience of perfect concentration. This is the state of Meditation".
In spite of its rich history and traditions, it is only during the past three decades that scientific study has focused on the clinical effects of meditation on health. During the 1960s, reports reached the West of yogis and meditation masters in India who could perform extraordinary feats of bodily control and altered states of consciousness. These reports captured the interest of Western researchers studying self-regulation and the possibility of voluntary control over the autonomic nervous system. At the same time, new refinements in scientific instrumentation made it possible to duplicate and substantiate some of these reports at medical research institutes. Health care professionals who were often dissatisfied with the side effects of drug treatments for stress-related disorders embraced meditation as a valuable tool for stress reduction, and today both patients and physicians enjoy the health benefits of regular meditation practice.
Herbert Benson, M.D., a professor at Harvard Medical School, describes the meditation experience as the "relaxation response." He discovered by studying various yogis and longtime meditators that the meditation process counteracted the effects of the sympathetic nervous system-the one that wants to fight or flee. Whereas the sympathetic system dilates the pupils and gets the heart rate, respiration, and blood pressure up, the parasympathetic system, activated when we meditate, does just the opposite. Muscle tension decreases, blood pressure drops, and for some extraordinary practitioners, even temperature and basal metabolism rates drop during a prolonged meditation. Oxygen needs of the body are reduced when you are in a highly relaxed state, and brain waves change from the busy beta-waves to the blissful alpha waves.
Functional magnetic resonance imaging (fMRI) has been used to identify and characterize the brain regions that are active during meditation. This research suggests that various parts of the brain known to be involved in attention and in the control of the autonomic nervous system are activated, providing a neurochemical and anatomical basis for the effects of meditation on various physiological activities. Recent studies involving imaging are advancing the understanding of mind-body mechanisms. For example, meditation has been shown in one study to produce significant increases in left-sided anterior brain activity, which is associated with positive emotional states. Moreover, in this same study, meditation was associated with increases in antibody titers to influenza vaccine, suggesting potential linkages among meditation, positive emotional states, localized brain responses, and improved immune function.
