There are also Lagnas such as Arudha, Karaka, and Karakansha Lagna that add a different level of richness to assessment. The principle of Lagna is extended to judging the lives of our relatives. For instance, Pitra Bhava, Pitrikaraka, Chara Pitrikaraka, and Pitra Arudha can be used as Lagnas to judge the life of one's father.
The principles of Jyotisha are universal; therefore, what is known about a native can be known about the native's father, mother, brother, and other relatives, by choosing the appropriate Lagna. This book delineates the use of the special Lagnas and extends the principles to other relatives.
