To my greatest surprise, while travelling in the West I saw people looking for books of this kind, wanting to buy books about Yoga, Yogis, spiritual attainment. Many have lost their mind by reading such books. They cannot keep balance. Trying to do what is in the book is just like going into the drug-store to get some Yoga-pills in order to attain spirituality! There are also many who look into the mirror to become clairvoyant, who gaze into a crystal in order to see the depth of life. They make light of something that is highest and best and most sacred.
