Somewhere there's a sutta (and it's doubtlessly worded much better than this) where the Buddha says that there is both happiness and suffering in this world. He speaks about if there were all happiness, or if there were all suffering... but says that there is both. Alas, I can't quite remember exactly what he said, nor can I think of appropriate keywords by which to search for it online. I put that forward in the hope that you or someone else recognise the sutta I'm referring to and have better luck at finding it than me.
