The Sutra on the Wisdom Stored in the Ocean of Buddha-Nature
The Sutra of Liberation and Breaking the Attributes of the Mind through the Wisdom Stored in the Ocean of Buddha-nature (Foxinghai zang zhihui jietuo po xinxiang jing 佛性海藏智慧解脫破心相經; hereafter: Sutra on the Wisdom Stored in the Ocean of Buddha-nature) is a Chinese apocryphal scripture whose origin is still obscure. For a long time, the sutra was thought to be missing. Following the discovery of the Dunhuang 敦煌 manuscripts and the stone sutras in the Grove of the Reclining Buddha (Wofoyuan 臥佛院; hereafter: the Grove), an overall version of the text can now be restored.
The sutra, consisting of two scrolls, is included in the Taishō edition in the volume on the “sutras in Dunhuang manuscripts whose origins are in doubt 敦煌寫本類疑似部”. The version in the Grove is an incomplete engraving of the first scroll of the sutra. For reasons that still await clarification, the text on wall e in cave 46 reads from left to right. It is preceded on wall d by scroll 22 of the Nirvana Sutra, and followed on wall f by the Diamond Sutra. Neither the author nor the translator of this scripture is mentioned in the Dunhuang and the Grove versions. (Shih-Chung, introductory remarks, 101)
