Some paragraphs which do not exist in other translations were found in Vasubandhu's commentary on Mahayanasamgraha translated into Chinese by Para Martha. They are about the explanations on the verse of Mahayanabhidharmasutra which seems to include the thought of Tathagatagarbha. This paper deals with this problem according to the analyses of Master Yin-shun and Ueda Yoshifumi and tries to find a new solution.
