依舊攝論說：三十三阿僧祇，第二劫為小一劫，為二十一劫；第三劫為中一劫，為九故，初為大一劫，為三故。

According to the old translation of the Mahāyānasaṃgraha, it speaks of thirty-three asaṃkhyeyas: the second kalpa is a small kalpa, making twenty-one kalpas; the third kalpa is an intermediate kalpa, making nine; the first is a great kalpa, making three.
