Man has body, mind and intellect. There are six enemies of man called shad ripu. These are Anger, Lust, Vanity, Greed, Attachment and Jealousy. Body is reined by the mind and directed to perform good or bad by the intelligence of rider. The Body-Mind-intelligence combination is needed to constantly overcome the Shad Ripu to gain happiness. Desire gives birth to  “Shad Ripu”. The greater our desires, the greater is the anger against the obstacles in the path of fulfilment of that desire. Our behaviour is controlled by the interaction of Body, mind and intellect with the “Shad Ripu”. Psychology is the scientific study of mind and behaviour. It deals with the malfunctions of mind like phobias, the depressions, the anxieties, the aberrations to the sub conscious mind and linked dreams with it. Astrology recommends to analyse a horoscope from Ascendant, Moon and Sun. Ascendant represents body which has organs(the indriya) which run after each desire. They are reined by mind. Mind is Moon. The reins are in the hands of- the Atman- the Sun.
