From the metaphysical point of view there are different rhythms describing the condition of man; they are spoken of in the Vedanta as sattva, rajas and tammas. Sattva is a harmonious rhythm, rajas a rhythm which is not in perfect harmony with nature and tammas is a rhythm which is chaotic by nature and destructive. Every impulse that comes to man while he is in this chaotic rhythm is followed by destructive results. Any impulse coming to a person when he is in the rhythm of rajas is accomplished, but the impulse that comes when he is in the rhythm of sattva is inspired and is in harmony with the rhythm of the universe.
