Mindfulness of Mind
12. "And how, monks, does a monk abide contemplating mind as mind? Here a monk knows a lustful mind as lustful, a mind free from lust as free from lust; a hating mind as hating, a mind free from hate as free from hate; a deluded mind as deluded, an undeluded mind as undeluded; a contracted mind as contracted, a distracted mind as distracted; a developed mind as developed; an undeveloped mind as undeveloped; a surpassed mind as surpassed, an unsurpassed mind as unsurpassed; a concentrated mind as concentrated, an unconcentrated mind as unconcentrated; a liberated mind as liberated, an unliberated mind as unliberated. . . . And he abides detached, not grasping at anything in the world. And that, monks, is how a monk abides contemplating mind as mind.--Mahasatipatthana Sutta: The Greater Discourse on the Foundations of Mindfulness,
in Thus Have I Heard: The Long Discourses of the Buddha, translated by Maurice Walshe
