Ten Austerities, bottom right side
Scene 22, Baodingshan, Dazu (map)

Statues #8, #9, #10 Vidyarajas are identified by Howard (p. 61) from left to right as Aparajita, Mahacakravajra, and Padanakshita respectively.

Traditionally there are only five vidyarajas rather then ten, so there is something unusual - theologically speaking - going on at this site.
