This was my point about Griffiths. He was not only both Catholic and Hindu but was a Priest and a Sanyassi. However as I discovered in checking this out Griffiths did not travel to India in search of the other half of his soul until 1968 so at the time Lewis was learning about Hinduism from him his knowledge would have been more theoretical.
It is from page 6 of a discussion starting here:
Into the Wardrobe — a C. S. Lewis website
Message Forums — A Community of Wardrobians
Board index ‹ C. S. Lewis & related ‹ Apologetics & Other Works
Lewis' thoughts on other major religions?
Reading, I am mostly in agreement with rusmeister - except in his preference of EO over RC./HGL
