Hope is a state of mind independent of the state of the world. If your heart's full of hope, you can be persistent when you can't be optimistic. You can keep the faith despite the evidence, knowing that only in so doing has the evidence any chance of changing. So while I'm not optimistic, I'm always very hopeful.
If your heart is full of fear, you won't seek truth; you'll seek security. If a heart is full of love, it will have a limbering effect on the mind.
Fear destroys intimacy. It distances us from each other; or makes us cling to each other, which is the death of freedom.... Only love can create intimacy, and freedom too, for when all hearts are one, nothing else has to be one--neither clothes nor age; neither sex nor sexual preference; race nor mind-set.
