35.85. Empty Is the World
Then the Venerable Ānanda approached the Blessed One … and said to him: “Venerable sir, it is said, ‘Empty is the world, empty is the world.’ In what way, venerable sir, is it said, ‘Empty is the world’?”
“It is, Ānanda, because it is empty of self and of what belongs to self that it is said, ‘Empty is the world.’ And what is empty of self and of what belongs to self? The eye, Ānanda, is empty of self and of what belongs to self. Forms are empty of self and of what belongs to self. Eye-consciousness is empty of self and of what belongs to self. Eye-contact is empty of self and of what belongs to self…. Whatever feeling arises with mind-contact as condition—whether pleasant or painful or neither-painful-nor-pleasant—that too is empty of self and of what belongs to self.
“It is, Ānanda, because it is empty of self and of what belongs to self that it is said, ‘Empty is the world.’”
Suññatalokasutta
“‘suñño loko, suñño loko’ti, bhante, vuccati. Kittāvatā nu kho, bhante, suñño lokoti vuccatī”ti?
“Yasmā ca kho, ānanda, suññaṁ attena vā attaniyena vā tasmā suñño lokoti vuccati. Kiñca, ānanda, suññaṁ attena vā attaniyena vā? Cakkhu kho, ānanda, suññaṁ attena vā attaniyena vā. Rūpā suññā attena vā attaniyena vā, cakkhuviññāṇaṁ suññaṁ attena vā attaniyena vā, cakkhusamphasso suñño attena vā attaniyena vā …pe…
yampidaṁ manosamphassapaccayā uppajjati vedayitaṁ sukhaṁ vā dukkhaṁ vā adukkhamasukhaṁ vā tampi suññaṁ attena vā attaniyena vā. Yasmā ca kho, ānanda, suññaṁ attena vā attaniyena vā, tasmā suñño lokoti vuccatī”ti.
Sujin Boriharnwanaket: Suññatta and anatta. One has realized the truth of non-self, but not the arising and falling away of realities. One sees the danger of the arising and falling away, otherwise there cannot be vipassana ñana. The whole world is gone, there is nothing there.
One really understands that whatever is there it is only by conditions. No one can change it.
