"If reason has been so far developed as to become active and discriminative, there is no reincarnation on this earth, for the three parts of the triune man have been united together, and he is capable of running the race. But when the new being has not passed beyond the condition of monad, or when, as in the idiot, the trinity has not been completed, the immortal spark which illuminates it, has to reenter on the earthly plane as it was frustrated in its first attempt. Otherwise, the mortal or astral, and the immortal or divine, souls, could not progress in unison and pass onward to the sphere above. p. 352"
