Each book draws upon poetry and prose, sacred and secular, from all around the world and from all ages - from the "Upanishads" and the "Tao Te Ching" to the speeches of Mahatma Gandhi, from the "Hebrew Bible" to the great 19th- and 20th-century poets such as Walt Whitman, Rainer Maria Rilke, Wallace Stevens, and Seamus Heaney. The series shares wholeheartedly and delightedly in the all-embracing spirit of the 21st century, appealing to the rapidly growing audience of people who believe in spiritual values - without necessarily subscribing to a particular religion.
