What to read after Critical Sermons of the Zen Tradition?

This book brings together two giants of the history of Zen: Linji (Japanese, Rinzai) and Hisamatsu Shin'ichi. Linji is looked upon as the founder of the Rinzai sect in Japan. Hisamatsu was a leading twentieth century master/thinker who lived in Kyoto and was a tremendous influence on the development of the Kyoto school of Japanese philosophy. The translators and editors have translated and annotated twenty-two of Hisamatsu's Zen teisho (Dharma talks, in effect, sermons for Zen practitioners) of a classical Zen text, the Record of Linji, the recorded sayings of the Chinese founder of Rinzai Zen.
