- An excellent summary of the positions put forward by the proponents of the idea that buddha-nature is not Buddhist, on the one hand, and criticism of this position, on the other, is found in Hubbard and Swanson, 1997. It is my understanding that the representatives of the so-called Critical Buddhism movement (hihan bukkyō 批判仏教) started out with the aim of reforming certain deplorable states of affairs in Japanese Buddhism, but quickly turned against much of what characterizes the history of Buddhist ideas in India and beyond. Though their immediate aim was thus laudable, the normativity of their approach makes it difficult for a critical scholar of the intellectual history of Buddhism to accept their criticisms.
- The most comprehensive discussion of the scriptures on buddha-nature in India is still Takasaki, 1974.
