Rebbe Nachman teaches us (Likutei Mohoran I, 4) that we have to say everything that happens is for the best. Hashem acts with great compassion and lovingkindness — it’s just that we can’t understand His ways, but the tzaddikim understand exactly what’s happening. We have to receive everything with love.
It is important to thank Hashem that we’re still alive and not to think that we don’t matter.
We need to make a new start to truly live! Hashem gets incredible nachas from us!
