Meditation

Meditation is the practice of focusing attention, often formalized into a specific routine. Meditation is usually recognized as a component of Eastern religions, originating in Vedic Hinduism, but it also developed independently in Sufism. Meditation can also be used for personal development in a non-religious context, such as the exercises of Hatha yoga.

Meditation refers to any of a family of practices in which practitioners train their minds or self-induce a mode of consciousness to realize benefit.

Meditation is generally an inner-oriented, personal practice, which individuals can do by themselves. Prayer beads or other ritual objects may be used during meditation. Meditation may involve invoking or cultivating a feeling or internal state, such as compassion, or attending to a specific focal point. The term can refer to the state itself, as well as to practices or techniques employed to cultivate the state.

There are dozens or more specific styles of meditation practice; the word meditation may carry different meanings in different contexts. Meditation has been practiced since antiquity as a component of numerous religious traditions.

Since the 1960s, meditation has been the focus of increasing scientific research of uneven rigor and quality. In over 1,000 published research studies, various methods of meditation have been linked to changes in metabolism, blood pressure, brain activation, and other bodily processes. Meditation has been used in clinical settings as a method of stress and pain reduction.

 

The history of meditation is intimately bound up with the religious context within which it was practiced. Even in prehistoric times civilizations used repetitive, rhythmic chants and offerings to appease the gods. Some authors have even suggested the hypothesis that the emergence of the capacity for focused attention, an element of many methods of meditation, may have contributed to the final phases of human biological evolution.

In the west, by 20BCE Philo of Alexandria had written on some form of “spiritual exercises” involving attention and concentration and by the 3rd century Plotinus had developed meditative techniques.

The Pāli Canon, which dates to 1st century BCE considers Indian Buddhist meditation as a step towards salvation. By the time Buddhism was spreading in China, the Vimalakirti Sutra which dates to 100CE included a number of passages on meditation, clearly pointing to Zen. The Silk Road transmission of Buddhism introduced meditation to other oriental countries, and in 653 the first meditation hall was opened in Japan. Returning from China around 1227, Dōgen wrote the instructions for Zazen.

The Islamic practice of Dhikr had involved the repetition of the 99 Names of God since the 8th or 9th century. By the 12th century, the practice of Sufism included specific meditative techniques, and its followers practiced breathing controls and the repetition of holy words. Interactions with Indians or the Sufis may have influenced the Eastern Christian meditation approach to hesychasm, but this can not be proved. Between the 10th and 14th centuries, hesychasm was developed, particularly on Mount Athos in Greece, and involves the repetition of the Jesus prayer.

Western Christian meditation contrasts with most other approaches in that it does not involve the repetition of any phrase or action and requires no specific posture. Western Christian meditation progressed from the 6th century practice of Bible reading among Benedictine monks called Lectio Divina, i.e. divine reading. Its four formal steps as a “ladder” were defined by the monk Guigo II in the 12th century with the Latin terms lectio, meditatio, oratio, and contemplation. Western Christian meditation was further developed by saints such as Ignatius of Loyola and Teresa of Avila in the 16th century.

By the 18th century, the study of Buddhism in the West was a topic for intellectuals. The philosopher Schopenhauer discussed it, and Voltaire asked for toleration towards Buddhists. The first English translation of the Tibetan Book of the Dead was published in 1927.

Secular forms of meditation were introduced in India in the 1950s as a Westernized form of Hindu meditative techniques and arrived in the United States and Europe in the 1960s. Rather than focusing on spiritual growth, secular meditation emphasizes stress reduction, relaxation and self improvement. Both spiritual and secular forms of meditation have been subjects of scientific analyses. Research on meditation began in 1931, with scientific research increasing dramatically during the 1970s and 1980s. Since the beginning of the ’70s more than a thousand studies of meditation in English-language have been reported. However, after 60 years of scientific study, the exact mechanism at work in meditation remains unclear.

Yoga is a healing system of theory and practice, its a combination of breathing exercises, physical postures, and meditation, practiced for over 5,000 years.

A survey released in May 2004 by the National Center for Complementary and Alternative Medicine focused on who used complementary and alternative medicine (CAM), what was used, and why it was used in the United States by adults age 18 years and over during 2002.

Yoga is considered a mind-body intervention that is used to reduce the health effects of generalized stress. Yoga is believed to calm the nervous system and balance the body, mind, and spirit. It is thought by its practitioners to prevent specific diseases and maladies by keeping the energy meridians open and life energy (Prana) flowing. Yoga is usually performed in classes; sessions are conducted at least once a week and for approximately 45 minutes. Yoga has been used to lower blood pressure, reduce stress, and improve coordination, flexibility, concentration, sleep, and all of these are the main parts of meditation.
