This marks the 24th year of the Tao wall calendar, which features contemplative nature photographs, Chinese calligraphy, and text from Gia-fu Feng and Jane English's translations of the Tao Te Ching and Chuang Tsu's Inner Chapters. The Tao Te Ching, the esoteric but infinitely practical book written in the sixth century B.C. by Lao Tsu, has been translated more times than any work except the Bible. Written in the fourth century B.C., Chuang Tsu's Inner Chapters is a companion volume to the Tao Te Ching. Chuang Tsu was to Lao Tsu as Saint Paul was to Jesus, and Plato to Socrates. The Tao Te Ching is one of the world's classic spiritual texts and a masterpiece of Chinese and eastern philosophy. Each month, text is paired with meditative black-and-white photographs. Amber Lotus calendars have been illuminating spirit in the world for 25 years.
