[The old transcript "Kosha-hon" quoted by Chusai Shibue in his lecture manuscript for Spiritual Pivot (Lingshu) "Reisu Kogi"].

The details about the old transcript "Kosha-hon" quoted by Chusai Shibue in his Reisu Kogi had remained unspecified. However, the author found that the Kosha-hon is probably now in the possession of the Peking University Library. In addition, through the investigation, the following facts emerged: 1) The date of writing of the transcript can be presumed to be between the Kanbun and Enpo eras in the Edo period. 2) The book, called "Kosha-hon", can be presumed to transcribe the lost version of the text in the group of the twelve volumes of XinKan Huangdi Neijing Lingshu. 3) Shibue left side notes, headed "Kosha-hon Hoki", and he used them for revision, but in fact these notes originated in the Ma Taixuan's Huangdi Neijing Lingshu Zhuzheng Fawei.
