The following link is a beautiful presentation on Esoteric teachings of the ancient wisdom. Sai Baba is mentioned briefly in Part 1 and Part 2. He is mentioned extensively in Part 3. It explains His Mission and how it relates to the ageless wisdom. Starting out with a discourse given by Him in the 70's.
