In order to find goodness one must find wickedness to compare it with. When we have found both, then both become clear; wickedness will show what goodness is. In order to find reality we must gather the knowledge of what is unreal, and this is not difficult. In our ordinary language we use the word false; false is that which is not real. All that is subject to change and destruction may be something in appearance, but it is never that which it pretends to be. All this existence which is before us and which is subject to change and death is not reality; it cannot be reality; but we can only see this when we have acquired some knowledge of reality,. If we do not look at it as unreal, we shall not have the desire to find what is real. We must find out what is unreal and acknowledge it as unreal; then alone can we go on to the next step which will be to find reality.
