Ignorance

How can Ignorance be bliss? If you are ignorant of things around you, then you are not knowledgable of them, and then you decide that they aren't even real, or exist. Sometimes people claim ignorance of things they can't understand; some more important than others. Such as, if we dismiss things that have no importance then we losing nothing of importance, but if we dismiss God just because we don't understand Him and cling to ignorance, then in the end we will not experience bliss. Just the opposite, except we won't understand why. We will not know why we suffer, but it was because we chose not to. Such a fate. How can Ignorance be bliss?
