Etheric Body, Plant Life, and Human Healing Processes

Let us examine the close relationship, to which spiritual science will give the key, between the process taking place within the eye, and the processes of smell and taste—particularly of the latter. Let us compare the ramifications of the nerve of taste into neighbouring tissues, with the optic nerve within the eyeball. The relationship is so close that we could hardly avoid looking for an analogy with the process of taste, if we wanted an inward characterisation of the process of sight. Of course the nerve of taste is not continued into anything like the highly intricate structure of the eye, which is situated in front of the retina, and therefore sight is in many ways different.
