Autobiography of A Yogi
"This autobiography presents a fascinating portrait of one of the great spiritual figures of our time. With engaging eloquence, and wit, Paramahansa Yogananda narrates the inspiring chronicle of his life: the experiences of his remarkable childhood, encounters with many saints and sages during his youthful search throughout India for an illumined teacher, ten years of training in the hermitage of a revered yoga master, and the thirty years that he lived and taught in America. Autobiography of a Yogi is at once a beautifully written account of an exceptional life and a profound introduction to the ancient science of Yoga and its time-honored tradition of meditation. The author clearly explains the subtle but definite laws behind both the ordinary events of everyday life and the extraordinary events commonly termed miracles." -GoodReads
