Gongai Sochu

Gongai Sōchū (1315–1390) was a student of Tettō Gikō and an important transmitter of the Daitokuji Rinzai lineage. He continued the teaching style established by Daitō Kokushi, emphasizing direct realization over institutional prestige or scholarly attainment. His role in the lineage was primarily one of faithful transmission, preserving the distinctive character of the Daitokuji approach.

Gongai's most significant contribution to Zen history was his training of Kasō Sōdon, who would become a legendary teacher in his own right and the master who confirmed Ikkyū Sōjun's awakening. Through this line of transmission, Gongai helped ensure that the uncompromising spirit of Daitō Kokushi's Zen survived into the fifteenth century.
