Part 2, the detailed explanation, contains three [sections]: first, calm; next, insight; and finally, their conjoined practice. Within calm there are five [parts]: 1. the method of cultivating calm; 2. revealing the supreme efficacy of calm; 3. identifying demonic phenomena; 4. distinguishing the counterfeit from the genuine; 5. indicating the benefits and encouraging practice. The first part contains two [subparts]: first, clarifying that superior people can enter; next, showing that obstructed people cannot. The first of these also contains two: first, relying on quietude to bring rest to the mind as the expedient means for cultivating calm; second, from “when long practiced and fully ripened” onward, clarifying that calm is accomplished and samādhi is attained, eliminating obstacles and becoming non-retrogressing. The first of these has two: first regarding external conditions, and second calming the mind internally.
