The jōtiṭam describes the tacā pukti, the periods marked by good or bad effects resulting from the placement of planets, the antaram, the internal division of pukti, time of birth (lakṉam) and the rāci, the zodiacal sign. The zodiac sign is defined according to the distance between the path used by the nine planets which is divided into 27 equal parts corresponding to 27 stars.
