Heaven A or B?

Complete oblivion. A world in which the past is not only thoroughly forgotten, it is known not to have ever existed. A place and time where the utopian state one finds self in is the only reality ever known, and ever to be known. Utter forgetfulness of past sorrow, pain, joy and various other emotions. Absolute failure to recall towards the life now known. This is a true Heaven.
Heaven is perfect. So then, a perfect world would have no need for a basis of comparison for that perfection. If a past life with imperfections could be remembered in Heaven, then Heaven, as it is known, could not be flawless. It would have blemishes, and even though existing there would seem perfect, reality there would be clouded with thoughts and memories of what life, imperfect life, used to be.
Perfection requires no basis for comparison. It is its own essence; a shining emblem of purity, and immaculately individual. To capture everything perfection, on its own, offers, one would need merely to be exposed to it alone. Reality where everything is perfect, and has always been known to be perfect, is the existence humans are continuously desiring, whether this is recognized or not.
On another level, knowing that, once Heaven is reached, complete oblivion will also be reached, an unbounded hope for this present reality is provided. When grief and sorrow floods a life, full reassurance that the pain will only be momentary occurs. In fact, after this life is over it will not even be remembered. Such a hope leaves individuals with peace when negative circumstances out of, or within, control occur. On the other hand, since joy, to finite minds, is justifiably thought to be closer to perfection than grief, moments of genuine joy in life provide a means for anticipation of something greater. Hope, once again, of the ecstasy of Heaven will bring even more contentment to life. If joy here, in this imperfect life, is pleasurable, how much more so will it be in a perfect world?
It is apparent that in order for Heaven to be truly perfect, everything experienced before arriving there must be eliminated from the mind. The memory is a powerful tool, strong enough to cause emotions in a person long after the circumstance in which the memory was formed in has passed. The past, the present, the future; all three make up the components of reality. The circumstances of the past have a way of haunting the present and the future. An existence of true perfection can only be constructed when no other existence is known. Complete oblivion.
