Meditation

Meditation refers to any of a family of practices in which the practitioner trains his or her mind or self-induces a mode of consciousness in order to realize some benefit.
Meditation is generally an internally-invoked, personal practice, which an individual 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.
A 2007 study by the U.S. government found that nearly 9.4% of U.S. adults (over 20 million) had practiced meditation within the past 12 months, up from 7.6% (more than 15 million people) in 2002.
