Dear MG,
Your Jupiter Mahadasa starting in Aug 2014 is going to be excellent as opposed to your Rahu dasa which was a highly malefic planet as per your horoscope. Jupiter is highly potent and a highly benefic planet too and you will enjoy all the benefits particularly with respect to your first, fourth, seventh and 10th houses. What these house represent is given in my articles on this forum ‘Astrology – a new version’.
