[303] Sakavādin: The future (anāgata) exists? Paravādin: Yes. Sakavādin: Is it not so that the future is not born, not come to be, not come into being, not arisen, not fully arisen, not manifest? Paravādin: Yes. Sakavādin: If the future is not born, not come to be, not come into being, not arisen, not fully arisen, not manifest, then indeed, good sir, it should not be said that "the future exists."
