I think that what determines whether a realm is heavenly or hellish is based on what kind of beings are there, not just on the external world. So I would disagree with saying that we are in heaven and exclude the opposite and the contrast that we can see. Although there are those who say that the whole universe is perfect and heavenly, in their own way, and there are also those who see the opposite.

Nor do I believe that we need difficulties to give meaning to our lives. I think people think that heaven is boring because they tend to look for happiness in external things. But when you have no desires to satisfy externally, you can realize that you can be happy just by being. When you are satisfied you may not feel the need to do anything because it is futile. You already feel good as you are. We are so caught up in desires that we believe they are in control of our happiness.

If you look in the Bible (and I may not be the best exegete) we can see how when Adam was in paradise and felt a desire - which was caused by his feeling of loneliness - he was automatically satisfied with the creation of Eve. So it's strange to think that it would be boring in a place where we can have basically any desire or need satisfied. If you think of it this way.

However, I reiterate that when one is well inside, desires are not in charge of making one happy, but one is already happy. Desire fulfillment does not make us happy, but only leaves us in the same state we were in before we had a problem. If desire fulfillment is the solution, then the problem is the desire.

No desires, no problem. At least some see it that way.

But the best for you. Best regards!
