Third, The Book of Lieh Tzu. Lao Tzu I mentioned, Chuang Tzu I mentioned; Lieh Tzu I forgot, and he is the very culmination of both Lao Tzu and Chuang Tzu. Lieh Tzu is the third generation. Lao Tzu was the master; Chuang Tzu was the disciple. Lieh Tzu was the disciple of a disciple; perhaps that is why I forgot him. But his book is immensely beautiful and has to be included in the list.
