Meditation is a widely accepted practice among psychologists, and is often incorporated into treatment plans for patients who suffer from mental illness. There are also many healthy individuals who practice meditation, albeit usually for relaxation purposes. But in Buddhism, meditation is the primary method of achieving liberation from suffering. Buddhist meditation has a unique idea, the "Satipatthana" which makes it different from meditation in other religions or theories. Satipatthana takes its name from "mindfulness" (sati) and the four "foundations" (patthana).
