Tao Te Ching

“In its pristine sense, the meaning of following the Tao, later called Taoism or wayfaring, included the whole spectrum of the search for knowledge... the schools of learning that retained the most comprehensive range of interest general came to be known as Taoist... [It] was used as a primary source for terms and concepts through which Buddhism could be explained to the Chinese.”
