大毘盧遮那成佛經疏 2.47

2.47

第十八「云何人心？謂思念利他」者，謂好追求思念：「某甲於我有恩，我當以如是方便令得大利。某甲曾於我所有不饒益，今當報之。」及種種理人利物之計，皆是人心也。當念自觀心行，早求法利，不應紛紜思慮他緣，是彼對治。

Eighteenth: regarding "What is the human mind? It means thinking of benefiting others": this means loving to seek out and think: "So-and-so has been kind to me; I should use such upāya to make them gain great benefit. So-and-so once did me harm; I must now retaliate against them," as well as various plans to manage people and benefit things—all of these are the human mind. Mindfully contemplating one's own mental activities and seeking the benefit of the Dharma early, without being distracted by contemplating other conditions, is its antidote.
