This is The Bodhisambhara Shastra ("Treatise on the Provisions for Enlightenment"), written by Arya Nagarjuna, the early Indian monk (ca 2nd c.) who is one of the most famous figures in the history of Indian Mahayana Buddhism. This work describes the essential prerequisites for achieving the complete enlightenment of a buddha while also describing the most important practices to be undertaken by bodhisattvas.

The text is accompanied here by an abridged version of its only commentary, originally written by the early Indian Bhikshu Vasitva, a monk who lived sometime in the middle or first half of the first millennium.
