三摩地自在中有二：初釋自在相、後結廣教。初文有三：初標雖已圓滿，未自在相善觀察故，當得自在；次釋四處二十二種相；後「彼於如是四處」下，明自在相。第二文中有二：初列四處；後「由剃除鬚髮」下，釋二十二種相。

Within mastery of samādhi, there are two [parts]: first, explaining the characteristics of mastery; and then, concluding the extensive teaching. The first text has three: first, stating that although it is already perfected, because one thoroughly observes the characteristics not yet mastered, one will attain mastery; next, explaining the twenty-two characteristics across the four stations; and last, from "with respect to these four stations" downward, clarifying the characteristics of mastery. In the second text, there are two: first, listing the four stations; and afterward, from "due to shaving off hair and beard" downward, explaining the twenty-two characteristics.
