Our Soul is a spark of the Divine. It is pure and perfect. Evil deeds merely obstruct our vision of the true nature of our Soul. Through good deeds we can become conscious of this perfection again.
There are black zones of shadow close to our daily paths, and now and then some evil soul breaks a passage through. When that happens, the man who knows must strike before reckoning the consequences.
What we experience in dreams - assuming that we experience it often - belongs in the end just as much to the over-all economy of our soul as anything experienced "actually": we are richer or poorer on account of it.
Happiness of any given life is to be measured, not by its joys and pleasures, but by the extent to which it has been free from suffering-from positive evil.
