俱舍論疏 9.26

9.26

論「應往彼趣至定不往餘」，明決定也。故《婆沙》云「譬喻者說，中有可轉。對法師言，中有於界、於趣、於處皆不可轉，感中有業極猛利故。」《正理論》云「此界、趣、處皆不可轉。謂定無有色中有沒欲中有生，亦無翻此，此與生有一業引故。」

On the Śāstra's 'It must go to that destination... definitely does not go elsewhere': this clarifies certainty. Thus the Vibhāṣā says: 'The Dārṣṭāntikas say that the intermediate state can change [its destination]. The Abhidharmikas say: Regarding realm, destination, and place of birth, the intermediate state can never change, because the karma that projects the intermediate state is exceedingly forceful.' The Nyāyānusāra says: 'Regarding realm, destination, and place of birth, none can change. That is, it is definite that there is no case where an intermediate existence of the form realm ceases and an intermediate existence of the desire realm is born, nor vice versa, because this and the birth existence are projected by one single karma.'
