“Science does not need mysticism and mysticism does not need science, but man needs both."
Almost a decade and a half ago, I had read a book, The Tao of Physics, that had a lasting effect on me. The book was written by a particle Physicist, Fritjof Capra, who happened to have some spiritual experiences. The book was all about drawing parallels between particle physics and eastern philosophies (Tao, Zen, Vedas etc. ). Although the book was written in 1970s, and Science (esp. particle physics) has made tremendous advancements, the approach that the author took to draw the parallels, stands against time. In fact, the recent developments in Science further assert the core message of the book.
Fast forward to-date, and I hold a similar book, Science of Breath, written by two doctors and co-authored by Swami Rama, a renowned Yogi of the 20th century. The book was authored in 1940, and again stands against time! This book is all about understanding our respiratory system, with a focus on breath and what it means to our existence, and beyond. The first two sections are pure Medical Sciences. And the last section, written by the Yogi, is about pranayama and meditation. I am sure that this book would appeal to the skeptics, at least to some extent. While some things need to be experienced, there is enough in the book, to make a really compelling read.
