[35] Bhikkhus, there are some ascetics and brahmins who are theorists of the finite and the infinite (antānantikā), who declare the world to be finite or infinite on four grounds. And on what basis, with reference to what, do those honourable ascetics and brahmins, theorists of the finite and the infinite, declare the world to be finite or infinite on four grounds?
9. (1) Bhikkhus, here some ascetic or brahmin—by means of ardour (ātappa), by means of striving, by means of application, by means of diligence, by means of right attention—touches such a concentration of mind (cetosamādhi) that, when the mind (citta) is concentrated, he dwells percipient of the world as finite. He speaks thus: 'This world is finite, bounded all around. And why is that? Because I, by means of ardour, by means of striving, by means of application, by means of diligence, by means of right attention, touch such a concentration of mind that, when the mind is concentrated, I dwell percipient of the world as finite. By this I know this: that this world is finite, bounded all around.' This, bhikkhus, is the first ground, relying on which, with reference to which, some ascetics and brahmins, theorists of the finite and the infinite, declare the world to be finite or infinite.
