"It is the great principle and mystery of all Providence: that to reach the upper light, we must follow blind affections; and to realize the lower kind of good, we must forget it. The astronomer, in search of a   missing star, looks away from the field in which it lies, and by side-light it steals into his eye: and thus the Christian, with vision directly fixed on one region, seizes the brilliants of another. While we are intent on divine things, God accomplishes the human." Martineau.
