The difference between what we call an object and a living being is the difference in the degree of spirit they absorb. Darwin died without finding the missing link. But there is no missing link; if there were any link which was missing it would have been found. There is a constant outpouring of spirit on matter, which is its own substance; and according to the degree in which the spirit touches matter, the matter forms into an object or into a being. Thus the difference between the lower creation and the higher creation is also that of the degree of the spirit which they are capable of absorbing; and there is the same difference between a material person and a spiritual person.
