Sokei-an translated the Record of Lin-chi (Lin-chi lu) from 1931 to 1933, in his first series of lectures. He felt that Americans needed original Chinese Zen source materials, translated and commented upon by a Zen master, and there were no such materials in those early days. Sokei-an was the first Zen master to translate the Record of Lin-chi and to give a commentary in English to Western students. The real historic value of Sokei-an's Lin-chi is in his commentary with its manifestation of Lin-chi's Zen.
