Laṅkāvatāra Sūtra
The well-known "Laṅkāvatāra Sūtra", composed sometime around the 4th century CE, is sometimes included in this group, although it is somewhat syncretic in nature, combining Yogācāra doctrines with those of the "tathāgatagarbha" texts. The "Laṅkāvatāra Sūtra" was influential in Chan Buddhism.
