Some of the books I enjoyed reading:-
I Heard God Laughing : Renderings of Hafiz
Sophie's World - Jostein Gaarder
Choosing a Path - Swami Rama
Climbing the Blue Mountain - Eknath Easwaran
I suggest that all books written by Eknath Easwaran be read, they
are brilliant and yet simply written.
A Fortune Teller Told Me - Tiziano Terzani
The Alchemist - Paulo Coelho
Hu - a magazine of Sufi thought by the Rumi Foundation, India.
