The Anguttara Nikaya (; literally "Increased by One Collection," also translated "Gradual Collection" or "Numerical Discourses") is a Buddhist scripture, the fourth of the five nikayas, or collections, in the Sutta Pitaka, which is one of the "three baskets" that comprise the Pali Tipitaka of Theravada Buddhism. This nikaya consists of several thousand discourses ascribed to the Buddha and his chief disciples arranged in eleven nipatas, or books, according to the number of dhamma items referenced in them.
