Let's to consider, living in this material world it is already like an infinite pain. We can just see as all time some trouble is disturbing us, and we have many grades, the maximum in the hell as we can understand by the 5° Chant of the Srimad Bhagavatam.
But we cannot think about the material word just as an oposition to the Spiritual World, then we cannot understand there an Infinite Bliss and here with the same grade an Infinite Pain.
It is what I understand regarding this your interesting question.
