Insight often leaves us with a good feeling, so it’s understandable that we may conflate feeling good with being wise or insightful. But our underlying wellbeing and access to wisdom don’t go away when we are in low moods or experiencing emotional pain. They may (or may not be) obscured, but they are certainly not absent.
It seems to me that nothing can be truly wasted in the universe. That all of life is interconnected and of immense, if sometimes unknown, value. Perhaps when we experience dark nights of the soul our hearts are being educated in ways that language cannot capture. Just as the beauty of flowers is nourished in the darkness below ground, the beauty of our hearts may be nourished by sadness and other challenges.
This is not a call to figure out what your heart is being taught during tough times. Far from it! If analysis and figuring things out were adequate to the task, there would be no call for this silent, deep education. Rather, simply know that nothing, including your pain, is ever wasted. Trust that your heart and soul are unfolding just as perfectly as the crocus or the flowering tree. Give yourself over to your experience and know that it is not the measure of your value or your possibilities.
