There is no way of comparing the pleasures of this world–for all their sweetness, intensity, and variety–with the pleasure of the next world.
We have no common denominator.
Just as we cannot compare a color, such as blue, with a number.
We can have more blueness or less, a larger number or a smaller one; we cannot compare them.
All we can say about the joys of the next world is that they are so superior to the joys of this world that it is worth going through the torments of hell in order to attain them.
From The Candle of God by Rabbi Adin Steinsaltz, “Hidden Aspects of Shabbat” p. 22
