In the summer of 1962 on my way from Paris to La Napoule, where a conference of 25 psychologists from 21 countries was held for planning to collect and distribute current information on opportunities for advanced training, research, and international exchange in psychology, I visited Heidelberg and could have a talk, to my great pleasure and honor, with Professor Karl Jaspers who had come there from Basel. I had wrote to him and sent him a reprint of my article "Psychotherapeutic implications of Zen" which I had published in Psychologia in 1958. After my Lecture at the Psychological Institute of the University of Heidelberg, a graduate student accompanied me to the residence, and kindly recorded our talk. The following is the main part of Professor Jaspers's talk on his view on Zen. I asked first his view on Zen and on the integration of Oriental culture and Western culture.
