The Anguttara Nikaya is the fourth book of the Sutta Pitaka, the first division of the Tipitaka, the sacred scriptures of Buddhism. The word anguttara means ‘up by one’ and is used because all the 2344 discourses or suttas in this book are arranged according to a numerical system from one to eleven. It has also been defined as "Numerical Discourses." The Anguttara Nikaya deals with a wider variety of subjects than any other division in the Tipitaka.
