RE: When sadness is pure joy...

Indeed! People look at melancholy as a depressing state, but, as stated in my blog, it isn't always about depression and sadness. There are more to it.

I agree with you! Paradoxically, there is joy because there is depression.
We feel melancholy, sad, and afraid as we see the death of other living beings, but we also feel joy and relief that we are alive today!
