Regarding Sutra Source for Buddha-Nature
From Buddha-Nature
The purpose of the buddha-nature website is to provide a resource hub for trustworthy information for learning about and teaching the concept of buddha-nature, its associated texts, teachings, lineages, and relevant Buddhist ideas. Unique content will be shared here, but the site will primarily act as a broker for other projects and authors that have already created quality materials, which we will curate for a wide range of audiences.
