This is a very old book. One story is the author was a Buddhist monk. This book is considered to embody the principles of Dhruva Nadi & Satyasamhita Nadi. The translator is not credited (odd), the Preface by S.K. Raman did not strike me as written by the translator. This, of course, makes one wonder where Ranjan got the book. Includes original slokas, no sample charts.
