Bikram's Beginning Yoga Class *2000 Version

"Sweat, strain, laugh, and do more for your health, body, and general well-being than you even imagined possible as you take your beginning yoga class from Bikram. For more than twenty years, Bikram's Beginning Yoga Class has been among the preeminent and most beloved of all yoga guides-and now it has been revised and updated by Bikram, with virtually all-new photographs and an updated section on yoga's medical benefits." -BarnesAndNoble

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
