Sage Valmiki in Ramayana did not mention the exact position of Mars (Kuja), even though it was stated that five planets were in exaltation in Lord Sri Rama’s birth chart. We have analysed ‘Ruchaka Yoga’ mentioned in Brihat Parasara Hora Sastra and Sage Valmiki’s description of position of planets in Lord Rama’s birth chart, then compared it with Lord Rama’s characteristics mentioned in Ramayana to conclude precise position of planet Mars (Kuja) in Lord Sri Rama’s birth chart.
