Belief in Paradise is part of our faith. But is there any psychological proof of its existence? The idea of counterpart suggests that if one thing exists, its counterpart too must exist. Man is unique in that he alone possesses the sense of enjoyment. But no man achieves fulfillment in this world. The presence of the sense of enjoyment within us and the absence of fulfillment in this world is in itself proof of the fact that there must be a world where fulfillment is achievable. There is no other explanation to this than believing in the existence of Paradise.
