The suffering and calamity are, moreover, exceptional. They befall a conspicuous person. They are themselves of some striking kind. They are also, as a rule, unexpected, and contrasted with previous happiness or glory. A tale, for example, of a man slowly worn to death by disease, poverty, little cares, sordid vices, petty persecutions, however piteous or dreadful it might be, would not be tragic in the Shakespearean sense.
The rationale for loving others is the recognition of the simple fact that every living being has the same right to and the same desire for happiness, and not suffering, and the consideration that you as one individual are one life unit as compared with the mulititude of others in their ceaseless quest for happiness.
Suffering is how Life tells you that you are resisting or misperceiving what is real and true. It is the way Life suggests that you are not in harmony with what is.
Things are simply the way they are. They don't give us suffering. Like a thorn: Does a sharp thorn give us suffering? No. It's simply a thorn. It doesn't give suffering to anybody. If
we step on it, we suffer immediately.
Why do we suffer? Because we
stepped on it. So the suffering comes from us.
There will come a time when everybody will know why, for what purpose, there is all this suffering, and there will be no more mysteries. But now we must live ... we must work, just work!
