Although Vipassana was practiced and taught by the Buddha, it contains nothing of a sectarian or religious nature, and can be accepted and applied by people of any background. The technique works on the basis that all human beings share the same problems, and that a practical method, which can eradicate these problems, can be universally practiced. Moreover, it involves no dependence on a teacher. Vipassana teaches those who practice it to be self-dependent. Vipassana courses are open to anyone sincerely wishing to learn the technique. Members of many religions – monks, nuns and priests as well as lay people – have all successfully practiced Vipassana, as have those of no particular faith.
