The Jamakkol prasanam uses the three vital factors namely the Udhaya, the Aaruda and the Kavippu. These three fundamentals join the Jama planets and their interaction paves the way for the astrological predictions. This book teaches from the basis of the calculations involved in finding the Udhaya, the Aaruda and the Kavippu and also the procedure to fix the Jama planets. The Kaarakathuvas of the planets, the bhavas and the signs are important to arrive at exact results. So they are dealt exhaustively and exclusively. This will be helpful not only to the practitioners of the Jamakkol prasanam, but also to the astrologers in general. Case studies have been included to facilitate the easy comprehension of the Jamakkol system.
