Writing under the pen name Yenbeeyes, the author is a distinguished researcher and prolific writer in Vedic and Nadi Astrology. Now 77 years old, he dedicates his life to decoding the intricate predictive systems of the ancients.

His journey into the cosmic sciences began under the traditional guidance of his maternal grandfather, followed by rigorous training under three other distinguished Gurus who imparted the nuanced intricacies of the subject. Over the decades, he has authored numerous authoritative texts, including Matching of Charts (Parts 1 & 2), Chandra Kavyam, Importance of Lagna, and Jyotish Research Articles.
His magnum opus is his work on the Eswara Nadi. He has successfully published the complete Surya Khandam series (12 volumes, covering every Lagna) and is currently documenting the Chandra Khandam, with this book marking the 10th volume.

A researcher at heart, Yenbeeyes bridges the gap between ancient tradition and modern technology. He leverages advanced tools to preserve rare manuscripts and employs a data-driven approach to validate classical predictions. This volume represents his latest innovative endeavour to deconstruct the mathematical precision of the Nadi Rishis for the modern reader.
