This is perhaps the most detailed delineation of the Lagna Bhava from several classical texts. The topics include Lagna fundamentals, success in the homeland or abroad, judging three portions of life, drishti yogas, facial features, personality traits, health and diseases, madness, speech-related yogas, fame, and renown, miscellaneous yogas, and yogas from other sources.
Each of these topics has a detailed deliberation of the topic covered. For instance, the Lagna fundamentals contain Lagna Karakatvas, strengths and weaknesses, body structure and complexion, physical felicity, and physical appearance. Similarly, success in the homeland or abroad, the characteristics of the foreign land, etc.
A section is dedicated to a student-teacher dialogue on several aspects of this Bhava and the concerned yogas. I believe this contains almost everything one would ever need to know about the Lagna Bhava.
