"And how, bhikkhus, does a bhikkhu abide contemplating mind as mind? Here a bhikkhu understands mind affected by lust as mind affected by lust, and mind unaffected by lust as mind unaffected by lust. He understands mind affected by hate as mind affected by hate, and mind unaffected by hate as mind unaffected by hate. He understands mind affected by delusion as mind affected by delusion, and mind unaffected by delusion as mind unaffected by delusion. He understands contracted mind as contracted mind, and distracted mind as distracted mind. He understands exalted mind as exalted mind, and unexalted mind as unexalted mind. He understands surpassed mind as surpassed mind, and unsurpassed mind as unsurpassed mind. He understands concentrated mind as concentrated mind, and unconcentrated mind as unconcentrated mind. He understands liberated mind as liberated mind, and unliberated mind as unliberated mind."
