This book helps you in deciding your Trishamsha. Trishamsha can be a chart of fortune or a chart of misfortune. Parashar has strongly recommended using Trishamsha for all predictions. This book gives simple approach for analysis of this Varga. Trishamsha has a big role in marriage predictions. In Dasha analysis this chart is important. All these have been explained with number of example charts.
This book contains some interesting information, but unfortunately, the author constantly contradicts himself in this book and also compared to what he teaches in his other books as well. For example, in his "Marriage Matters" chapter, he judges the happiness and sustainability of a marriage mainly by the D30 Iyer Trimshamsha, but he doesn't do it like that in his other books. He does look at other charts (D1, D9, D30 Parashar Trishamsha) in this book as well, but it seems like they are not considered as important at all unless they fit his narrative. In some examples, the D1 and D9 charts look very bad for the marriage, and even the D30 Parashar Trishamsha chart doesn't really look that great either, but because the D30 Iyer Trimshamsha says something good, he claims the marriage is happy and long-lasting. There are charts where every chart seems between bad and mediocre at best, but he claims it's a happy marriage and ignores all the red flags from all charts. His way of judging marriages here just doesn't make any sense, and it goes against his previous books. The author's way of reading charts is very inconsistent.
