Sthiramati (Sanskrit; Chinese: Anhui 安慧, and Jianhui 堅慧; Tibetan: Blo gros brtan pa) was a 6th-century Indian Buddhist scholar-monk. Sthiramati was a student of a Yogācāra scholar named Gunamati, and he was also a contemporary of another 6th-century Yogācāra scholar, Dharmapala of Nālandā. Sthiramati is connected with Valābhi university (present-day Gujarat), and also with Nālandā. Evidence from two inscriptions indicate that a figure named Sthiramati founded a monastery at Valābhi. This is the true essence of the dependent nature (i.e. the perfected nature). Because of this, Sthiramati's view has also been compared to the Nirākāravāda ("false aspectarian") view of Yogācāra by modern scholars, since he holds that all mental images are unreal and false.
Meanwhile, in Dharmapala's system, the dependent nature is the basis or pivot for both the imagined nature (if the dependent nature is discriminated dualistically) and the perfected nature (if duality is removed). For him, the dependent nature is both empty in one sense (when it is falsely discriminated) but also not-empty is another sense (in its true non-dual structure). Thus, for Dharmapala, the dependent nature and the perfected nature are both real, and they are also understood as being neither the same nor different. Because of this, Dharmapala's view has been seen as prefiguring the Sākāravāda view. For Dharmapala, these four divisions were seen as working simultaneously to give rise to experience. However, Sthiramati's system only accepts the first three divisions. Furthermore, for Sthiramati, the first two divisions are imagined and ultimately unreal, while only the self-reflexive aspect is ultimately real. Thus, in Sthiramati's system, there is truly only one aspect (bhāga), one single dynamic self-aware consciousness in which causes and effects arise moment by moment.
Furthermore, Sakuma also argues that it is likely there were different Indian commentators whose work later became conflated into one figure named "Sthiramati".
