A dream becomes automatically known to a person as false and immaterial, and similarly one eventually realizes that material happiness in this life or the next, on this plane or a higher plane, is insignificant. When one realizes this, the Vedas, although an excellent source, are insufficient to bring about direct knowledge of the truth.
