瑜伽論記 1.476

The text states: 'Because their lifespan is exhausted' means the fixed term of life in that heaven has ended. 'Because their karma is exhausted' means the karmic force has ended before completing the heavenly lifespan. 'Because their merit is exhausted' means that clinging to the taste of concentration, they cast off their lives. Although there is first birth in the second and third dhyānas, because there is no investigation or reflection, there is no further yearning, and because there is no flattery or deceit, there are also no rulers and ministers; in the first dhyāna both are present, hence Mahābrahmā gives rise to thoughts of yearning. According to the text's sense, it means that as each palace is formed, sentient beings immediately inhabit it; it does not wait for complete formation before placing people to live there.
