There is, indeed, a great deal of mystery in life--much that we see "as in a glass darkly." But though we may not apprehend the full meaning of the discipline of trial through which the best have to pass, we must have faith in the completeness of the design of which our little individual lives form a part.
We have each to do our duty in that sphere of life in which we have been placed.

Duty alone is true; there is no true action but in its accomplishment.

Duty is the end and aim of the highest life; the truest pleasure of all is that derived from the consciousness of its fulfilment.

Of all others, it is the one that is most thoroughly satisfying, and the least accompanied by regret and disappointment.

In the words of George Herbert, the consciousness of duty performed "gives us music at midnight." And when we have done our work on earth--of necessity, of labour, of love, or of duty,--like the silkworm that spins its little cocoon and dies, we too depart.
