I read this beautiful Sufi teaching today:
Overcome any bitterness that may have come because you were not up to the magnitude of the pain that was entrusted to you.
Like the mother of the world who carries the pain of the world in her heart,
Each one of us is part of her heart, and therefore endowed with a certain measure of suffering.
With acceptance we can hold ourselves and our suffering, with tenderness and compassion. We can hold this suffering that has been entrusted to us and allow compassion to grow. We can extend that compassion to every being and to our mother of the world.
