I read a book "long pilgrimage" by John Bennett many years ago. This book is about Shivapuri baba. (More on Shivapuri baba on - http://literature.wnso.org/2005/life_of_the_Shivapuri_baba_Mohan.htm). There was a interesting discussion with Albert Einstein and Shivapuri baba about religion and science. Yes it is the same famous Albert Einstein. I do not remember the details of the discussion, it has been a while but Baba talked why science is based on faith and Einstein agrees. If you can find the book it is worth the read.
