The darkest clouds eventually run out of rain.
When we are in the middle of a brutal season, our minds trick us into believing that the warmth we once felt is gone for good. But the Buddha continually pointed to the ever-shifting nature of reality, reminding us that no emotion—whether it is agonizing grief or profound joy—can stay fixed in place forever. Your pain is not a permanent residence; it is simply weather passing through. The fact that you have known happiness before is undeniable proof that the capacity for it still lives inside of you.
You do not have to force yourself to feel completely fine today. Just hold on to the quiet, unshakeable certainty that the wheel will turn, the heavy days will eventually lift, and you are going to be okay again.
