1Then a certain bhikkhu approached the Blessed One … and said to him: "Venerable sir, it is said, ‘the world, the world.’ In what way, venerable sir, is it said ‘the world’?"

2"It is disintegrating, bhikkhu, therefore it is called the world. [n.45] Lujjatī ti kho bhikkhu tasmā loko ti vuccati. Spk: The five aggregates are called thus because it is their nature to disintegrate (lujjanasabhavatta). Loka is derived from lujjati in this sutta. The etymology cannot be accepted literally but serves a pedagogic purpose. On the six sense bases as "the world," see SN35.116. And what is disintegrating? The eye, bhikkhu, is disintegrating, forms are disintegrating, eye-consciousness is disintegrating, eye-contact is disintegrating, and whatever feeling arises with eye-contact as condition … that too is disintegrating. The ear is disintegrating … The mind is disintegrating … Whatever feeling arises with mind-contact as condition … that too is disintegrating. It is disintegrating, bhikkhu, therefore it is called the world."

1Atha kho aññataro bhikkhu yena bhagavā … pe … ekamantaṁ nisinno kho so bhikkhu bhagavantaṁ etadavoca:

2"‘Loko, loko’ti, bhante, vuccati. Kittāvatā nu kho, bhante, lokoti vuccatī"ti? "‘Lujjatī’ti kho, bhikkhu, tasmā lokoti vuccati. Kiñca lujjati? Cakkhu kho, bhikkhu, lujjati. Rūpā lujjanti, cakkhuviññāṇaṁ lujjati, cakkhusamphasso lujjati, yampidaṁ cakkhusamphassapaccayā uppajjati vedayitaṁ sukhaṁ vā dukkhaṁ vā adukkhamasukhaṁ vā tampi lujjati … pe … jivhā lujjati … pe … mano lujjati, dhammā lujjanti, manoviññāṇaṁ lujjati, manosamphasso lujjati, yampidaṁ manosamphassapaccayā uppajjati vedayitaṁ sukhaṁ vā dukkhaṁ vā adukkhamasukhaṁ vā tampi lujjati. Lujjatīti kho, bhikkhu, tasmā lokoti vuccatī"ti.
