Archival Overview
Great reformer of Japanese Rinzai Zen, painter, and calligrapher who systematized koan study and created the legendary riddle 'What is the sound of one hand clapping?'.
Biographical Record
Hakuin Ekaku (1686–1769 CE) revitalized a decaying Rinzai Zen tradition during the Edo period, turning Shoin-ji temple into a buzzing spiritual forge.
He emphasized intense zazen meditation to cure spiritual exhaustion (zen sickness), designed the famous 'sound of one hand' koan, and painted bold, humorous brushwork to teach lay commoners.
