This derivation, in effect, means, connotes and implies that the Vedas should contain within themselves all the knowledge needed by mankind relating not only to the so-called â spiritualâ (or other-worldly) matters but also to those usually described as purely â secularâ , â temporalâ , or â wordlyâ ; and also to the means required by humanity as such for the achievement of all- round, complete and perfect success in all conceivable directions and that there can be no adjectival or restrictive epithet calculated (or tenaing) to limit that knowledge down in any sphere, any direction or any respect whatsoever.
