得三摩地中分四：初、釋所治能治別相；次、釋得者得近分；三、結廣教不過不增；四、結世間淨住正法者。

In 'attaining samādhi,' it is divided into four parts: first, explaining the specific marks of what is to be counteracted and the antidotes; next, explaining that attaining it means attaining the preliminary stage; third, concluding that the broad teaching has neither excess nor surplus; fourth, concluding that worldly purity abides in the true Dharma.
