The material world is not permanent, it is asat and the spiritual world is sat or eternal. This material world is a reflection of the eternal spiritual world, it is a reflection. But the reflection is not permanent. Therefore from one point of view it is not real. It is not actually false, it is temporary. But temporary reality means it is relative, it is not absolute. So the person realizes that the form of God or Krishna is not temporary. It is sat cit ananda, it is not of the same nature at all. If one can eventually understand that then they will have no difficulty.
