"What qualities must a Bodhisattva possess? In the Teaching of Gotama Buddha and in the Teaching of Bodhisattva Maitreya, given by him to Asanga according to tradition in the fourth century (Mahayana-Sutralankara), the maximum development of energy, courage, patience, constancy of striving, and fearlessness was underlined first of all. Energy is the basis of everything, for it alone contains all possibilities."
