Investigations in Environmental Science Book

The best religious book i ever read.. And i ve read a lot of them.. Had it for 11 years on me..
The most shocking part of it that the swami describes and explains how the human body works and why it looks the way it is by using very modern physics terminology, which wasn't very common in religious books back in 1895..
After all these years i m still very impressed by this master piece and still discover new insights about nature and what that whole life thing we all share is about.. A must read for any one tired of the hamster wheel..
