We are many small puppets ...

We are many small puppets moved by fate and fortune through strings unseen by us; therefore, if it is so as I think, one has to prepare oneself with a good heart and indifference to accept things coming towards us, because they cannot be avoided, and to oppose them requires a violence that tears our souls too deeply, and it seems that both fortune and men are always busy in affairs for our dislike because the former is blind and the latter only think of their interest.
