An Shigao
Two manuscripts discovered by Kajiura Susumu in 1999 in the collection of the Kongōji in Osaka Prefecture, Japan, present four heretofore unknown works which, based on their apparent antiquity, may be attributable to An Shigao. The first three of these texts are related to meditation practices such as "ānāpānasmṛti" ("mindfulness of breathing") and the "twelve gates". The fourth appears to be a record of an oral commentary on topics covered in the preceding texts.
