佛遺教經論疏節要 1.131

1.131

制之一處者，無二念三昧，翻斷心性差別障。一處謂心也。制之於心，則四分差別自然休息。無事不辦者，起多功德三昧，翻斷失諸功德障。文小不次，若依論在後，今順經文居中。折伏汝心者，調柔不動三昧，翻斷躁動不調障。既知制心之益，是故精進折伏，不令動轉輕躁也。

"When controlled in a single place" refers to the samādhi of no dual thoughts, which counteracts and severs the obstacle of the differentiated nature of the mind. The "single place" refers to the mind. If one controls it at the mind, the four differentiated parts naturally cease. "There is nothing that cannot be accomplished" refers to the samādhi that produces manifold virtues, which counteracts and severs the obstacle of losing the virtues. The text is slightly out of sequence: according to the treatise it comes after, but here it follows the sūtra text and sits in the middle. "Bend and subdue your minds" refers to the samādhi of being pliant and unmoving, which counteracts and severs the obstacle of restlessness and lack of regulation. Having realized the benefit of controlling the mind, one therefore vigorously bends and subdues it, not allowing it to move briskly and rashly.
