The Teaching of the Armor Array

The Teaching of the Armor Array describes a dialog between the Buddha Śākyamuni and the bodhisattva Anantamati. The sūtra is primarily concerned with the great armor, a quality related to the perfection of insight. As such, it is no conventional sort of armor. Rather, donning it involves giving up all grasping at phenomena, and engaging diligently on the path, with insight into the nature of phenomena. The Buddha and Anantamati also discuss the nature of the Great Vehicle and the great path, all the while emphasizing their emptiness and lack of marks.
