Yoga in daily life by Swami Sivananda. From the intro:
“This book is a message from the great Yogi of the Himalayas. This inspiring and soul-stirring little volume will, we venture to say, undoubtedly contribute its mite to the moral and spiritual perfection of the human race in general and the aspirants in particular. If this book appeals to thebroad-minded and expanded hearts amongst the religious reformers and also aspirants, the Publishers’ labours will have been sufficiently recompensed.”
