We have a choice when we go through difficult things; we can either become wounded or wise. The inherent benefits within challenging times can only be seen with greater awareness and directing our attention in the proper direction. When we follow the minds unsolicited thoughts, they guide us towards suffering.
When we start looking for the benefit or opportunity in the problem, something different will be seen.
Know that your joy has never left you, but you have pushed your joy aside through your thinking. It can no more leave you than the blue sky above. It can appear to be gone by the cover of clouds, but above the clouds, it is still seen. So point your attention towards what you want, and once you do, the clouds will float by revealing the joy that never left.
