'And thus also will be their state in the other world.' He who thus knows the udgîtha, and meditates on it thus, his life in this world will be greater than great, and also his state in the other world, yea, in the other world.
In plain words: He said the same would be true for them in the next world. Whoever knows and meditates on the chant this way will have the best life here and after death.
