14. Where does the Root of the Illusion Lie?

Now let us examine where illusion lies hidden from the view of these religionists. It lies deeply rooted in the misconstruction of reality, grows up into the illusive ideas of appearances, and throws its dark shadow on life. The most fundamental error lies in their construing reality as something unknowable existing behind appearances.

According to their opinion, all that we know, or perceive, or feel, or imagine about the world, is appearances or phenomena, but not reality itself. Appearances are 'things known as,' but not 'things as they are.' Thing-in-itself, or reality, lies behind appearances permanently beyond our ken. This is probably the most profound metaphysical pit into which philosophical minds have ever fallen in their way of speculation. Things appear, they would say, as we see them through our limited senses; but they must present entirely different aspects to those that differ from ours, just as the vibration of ether appears to us as colours, yet it presents quite different aspects to the colour-blind or to the purblind. The phenomena] universe is what appears to the human mind, and in case our mental constitution undergoes change, it would be completely otherwise.

This argument, however, is far from proving that the reality is unknowable, or that it lies hidden behind appearances or presentations. Take, for instance, a reality which appears as a ray of the sun. When it goes through a pane of glass it appears to be colourless, but it exhibits a beautiful spectrum when it passes through a prism. Therefore you assume that a reality appearing as the rays of the sun is neither colourless nor coloured in itself, since these appearances are wholly due to the difference that obtains between the pane of glass and the prism.

We contend, however, that the fact does not prove the existence of the reality named the sun's ray beyond or behind the white light, nor its existence beyond or behind the spectrum. It is evident that the reality exists in white light, and that it is known as the white light when it goes through a pane of glass; and that the same reality exists in the spectrum, and is known as the spectrum when it goes through the prism. The reality is known as the white light on the one hand, and as the spectrum on the other. It is not unknowable, but knowable.

Suppose that one and the same reality exhibits one aspect when it stands in relation to another object; two aspects when it stands in relation in two different objects; three aspects when it stands in relation to three different objects. The reality of one aspect never proves the unreality of another aspect, for all these three aspects can be equally real. A tree appears to us as a vegetable; it appears to some birds as a shelter; and it appears to some worms as a food. The reality of its aspect as a vegetable never proves the unreality of its aspect as food, nor the reality of its aspect as food disproves the reality of its aspect as shelter. The real tree does not exist beyond or behind the vegetable. We can rely upon its reality, and make use of it to a fruitful result. At the same time, the birds can rely on its reality as a shelter, and build their nests in it; the worms, too, can rely on its reality as food, and eat it-to their satisfaction. A reality which appears to me as my wife must appear to my son as his mother, and never as his wife. But the same real woman is in the wife and in the mother; neither is unreal.
