Sangyō Gisho

It is based on the annotated text Fa Hua Yi Ji (法華義記) by Liang dynasty monk Fayun (法雲, 467–529 AD).

According to tradition, the Hokke Gisho was composed in 615 AD and is the oldest Japanese text, highly venerated among Tendai scholars but never shared to the public.

In the late 1960s, it was discovered that about 80% of this text was copied from a Liang dynasty commentary by the monk Min (旻, 467–527), which was recovered from the Dunhuang manuscripts.

The Hokke Gisho contains a colophon stating, "This book belongs to the private collection of King Jōgū [Prince Shōtoku] and is not from overseas."

[4]The oldest text to attribute the Sangyōsho to Shōtoku Taishi is the 747 Hōryūji Garan Engi Narabini Ruki Shizaichō (法隆寺伽藍縁起并流記資財帳).
