Though my first stint with spirituality was through a book, “The Divine Romance” followed by “Autobiography of a Yogi” by Sri Paramahamsa Sri Yoganandaji Maharaj.
I consider “Living with the Himalayan Masters” by Swami Rama has been a major milestone on this journey.
Googling for it, I found an online copy of it free for download here and here as well.
Did you know that these were the notes of Pt. Rajmani Tigunait whenSwami Rama was speaking about these experiences.
