28.63

As for 'at death, the pure gives rise to all, while defiled gives rise to its own and lower defilements,' the previous explanation of the mutual generation of the pure and the defiled was stated solely with respect to concentration. Now it is based on the end of life, hence it says 'at death.' That is, at the time of death, from the innately acquired pure, defilement of all stages of the three realms can possibly arise, because wherever one is reborn, one gives rise to the defilement of that [plane]. If at the time of death it is from the defiled, it can give rise to its own stage and lower stages. All lower defilements do not give rise to higher ones, because without having abandoned lower defilements, one is not born above.
