Sundarakāṇḍa: A Study of Power, Purpose, and Alignment is not a retelling of the Ramayana. It is an exploration of intelligence in motion. Across 68 sargas, this book examines Hanuman's journey as a living system-where physics, strategy, psychology, ethics, and devotion converge. Every leap becomes momentum, every pause becomes signal, and every decision reveals how disciplined power operates under purpose. Through scientific lenses-systems thinking, decision theory, energy transfer, moral equilibrium, and signal integrity-Sundarakāṇḍa is revealed as a manual of intelligent action, not mythology. This book is for readers who seek meaning without abandoning reason, devotion without superstition, and power without chaos. When faith and intelligence move together, nothing remains impossible.
