This group of deities on lotuses is supported by four yakshas accompanied by a snow lion. Instead of being pot-bellied, naked and crouching the yakshas are depicted like atlantes and wear short dhotis. (For more information on yakshas see an article on the Ashmolean Museum website at http://jameelcentre.ashmolean.org/object/EA1995.95).
Manjushri, at the centre, brandishes his sword to cut through ignorance and holds the stem of an open lotus with a manuscript balancing on it.
To his left, Avalokiteshvara does the gesture of supreme generosity with his right hand and holds the stem of a similar eight-petal lotus, the skin of an antelope covers his left shoulder.
Vajrasattva holds a thunderbolt sceptre (vajra) and a bell (ghanta) together with the stem of a blue lotus.

A similar triad, with the base missing. Manjushri’s book is supported by a blue lotus, Avalokiteshvara holds the neck of a ritual water pot in his right hand. Vajrapani’s main attribute is missing from his right hand.
On both sets, the blade of Manjushri’s sword is decorated with a geometrical pattern typical of sculptures produced in the Ngari area of Western Tibet around the 12th century.

Here Vajrasattva stands at the centre and Manjushri and Avalokiteshvara are depicted as attendants (smaller size).
NB: when standing, Vajrasattva and Vajrapani may have the same appearance and it is often impossible to know which is which unless an inscription on the base of the sculpture identifies the figure.
