For many New Agers, these channeled messages rival the scriptures of the main world religions as sources of spiritual authority, although often New Agers describe historical religious revelations as forms of "channeling" as well, thus attempting to legitimate and authenticate their own contemporary practices. Although the concept of channeling from discarnate spirit entities has links to Spiritualism and psychical research, the New Age does not feature Spiritualism's emphasis on proving the existence of life after death, nor psychical research's focus of testing mediums for consistency.
