More Schopenhauer:

"If that veil of Maya, the principium individuationis, is lifted from the eyes of a man to such an extent that he no longer makes the egotistical distinction between himself and the person of others, but takes as much interest in the sufferings of other individuals as in his own, and thus is not only benevolent and charitable in the highest degree, but even ready to sacrifice his own individuality whenever several others can be saved thereby, then it follows automatically that such a man, recognizing in all beings his own true and innermost self, must also regard the endless sufferings of all that lives as his own, and thus take upon himself the pain of the whole world."

The endless suffering of all that lives as my own. Of the whole world. On that note, sleep.
