Lecture XXII

Similarly, if only one can find sufficiently graphic concepts, one can speak of an evolution that takes place for these periods of time in the sphere through which the dead pass. There, too, an evolution takes place. On all kinds of occasions, where this has been possible, this evolution has been discussed in different ways. But relatively easy though it is to speak of evolution on the physical plane—and as you know it is not all that easy in this materialistic age—it is naturally less easy to do so with regard to the spiritual world, since for that world we lack sufficiently graphic concepts. Our language was created for the physical plane, and we are forced to use all kinds of paraphrases and graphic substitutes in order to describe the spiritual sphere in which the dead are living, especially with regard to evolution.
