瑜伽論記 1.427

1.427

又解：經說初從壞地獄乃至壞梵補，經十小劫眾生世間壞，梵王未上生也。以大梵王獨一少故攝入器中，論中多少，通論故言十九劫壞有情世間一劫壞器世間。

Another explanation: The sūtra states that from the destruction of the hells up to the destruction of the Brahmā-purohita, it undergoes ten small kalpas to destroy the sentient world, and the Brahmā King has not yet ascended for rebirth. Because the Great Brahmā King is solitary and rare, he is subsumed under the receptacle; whereas the śāstras discuss them comprehensively in terms of greater and lesser, hence stating that nineteen kalpas destroy the sentient world and one kalpa destroys the receptacle world.
