Cognitive mental as well as more spiritual approaches abound in response to the wide variety of potential causes for doubt. Behavioral therapy — in which a person systematically asks his own mind if the doubt has any real basis — uses rational, Socratic methods. This method contrasts to those of say, the Buddhist faith, which involve a more esoteric approach to doubt and inaction. Buddhism sees doubt as a negative attachment to one's perceived past and future. To let go of the personal history of one's life (affirming this release every day in meditation) plays a central role in releasing the doubts — developed in and attached to — that history.
