The ancient Indian system of meditation, called Dhyana in Sanskrit, was introduced by Bodhidharma to China and became popular as Chán (as in Jackie Chan) and from there it reached Japan and became Zen.
The Japanese Scholar Hajime Nakamura has said that “India is culturally, Mother of Japan. For centuries it has, in her own characteristic way, been exercising her influence on the thought and culture of Japan.”
Another Japanese Scholar Daisetz Teitaro Suzuki has said that “The study of Japanese thought is the study of Indian thought”.
