[235] He was dwelling at Sāvatthī … There the Blessed One … "Bhikkhus, the uninstructed worldling (assutavā puthujjano) might become disenchanted with this body composed of the four great elements (cātumahābhūtika kāya), might become dispassionate toward it, might be liberated from it. For what reason? Because, bhikkhus, growth and decline, taking up and laying down, are seen in this body composed of the four great elements. Therefore the uninstructed worldling might become disenchanted therein, might become dispassionate, might be liberated.
But, bhikkhus, as to that which is called 'mind (citta)', and also 'mentality (mano)', and also 'consciousness (viññāṇa)' — therein the uninstructed worldling is unable to become disenchanted, unable to become dispassionate, unable to be liberated. For what reason? Because for a long time, bhikkhus, this has been clung to, cherished as 'mine', and grasped by the uninstructed worldling thus: 'This is mine, this I am, this is my self.' Therefore the uninstructed worldling is unable therein to become disenchanted, unable to become dispassionate, unable to be liberated."
