Vak is a form of Manjusri as described in the Sadhanamala. Vak is variously known as Vajraraga, Amitabha Manjusri, and Dharmasankhasamadhi. His images are very rare and Nepal is perhaps the only country where this form of Manjusri is worshipped. He is shown to be seated in dhyanasana with his hands joined on the lap in Samadhi mudra.
