Majjhima Nikaya 2:87
SUJATO‘Atthi vedanā’ti vā panassa sati paccupaṭṭhitā hoti. Yāvadeva ñāṇamattāya paṭissatimattāya anissito ca viharati, na ca kiñci loke upādiyati.
Or mindfulness is established that feelings exist, to the extent necessary for knowledge and mindfulness. They meditate independent, not grasping at anything in the world.
