The Majjhima Nikāya (abbreviated MN) or Collection of the Intermediate Discourses of the Buddha is a collection of 152 discourses in the Pāli canon. The word "intermediate" refers to the length of each individual speech. It contains a wide variety of teachings presented as narratives between the Buddha and a wide range of his contemporaries. It is the most popular collection because it mixes biographical anecdotes with superficial doctrinal content. However, it is interesting to highlight its biographical value. This first subcollection called The First Fifty, contains 50 suttas and is divided into five chapters: the Chapter on the Root of All Things, the Chapter on the Lion's Roar, the Chapters on Similes, the Chapter on Pairs and the Minor Chapter on Peers. We can highlight the suttas, MN 10 Instructions of Practice, MN 16 Mental Obstructions and MN 17 The Thickness of the Jungle and MN 4 Fear and Dread, MN 26 The Noble Quest and MN 36 Great Discourse with Saccaka, which describe the enlightenment of the Buddha. On the spurious side, MN 20 How to Stop Thinking, which exposes a false technique, and MN 43 and MN 44 which appear to be catechisms to impart doctrine in question and answer format.
