Book excerpt: The autobiography of Paramahansa Yogananda (1893 - 1952) details his search for a guru, during which he encountered many spiritual leaders and world-renowned scientists. When it was published in 1946 it was the first introduction of many westerners to yoga and meditation. The famous opera singer Amelita Galli-Curci said about the book: "Amazing, true stories of saints and masters of India, blended with priceless superphysical information-much needed to balance the Western material efficiency with Eastern spiritual efficiency-come from the vigorous pen of Paramhansa Yogananda, whose teachings my husband and myself have had the pleasure of studying for twenty years."
