Context

“Love in dreams is greedy for immediate action, rapidly performed and in the sight of all. Men will even give their lives if only the ordeal does not last long but is soon over, with all looking on and applauding as though on the stage. But active love is labor and fortitude, and for some people too, perhaps, a complete science. But I predict that just when you see with horror that in spite of all your efforts you are getting farther from your goal instead of nearer to it—at that very moment I predict that you will reach it and behold clearly the miraculous power of the Lord who has been all the time loving and mysteriously guiding you.” source
