To Duty

Light of dim mornings; shield from heat and cold;
Balm for all ailments; substitute for praise;
Comrade of those who plod in lonely ways
(Ways that grow lonelier as the years wax old);
Tonic for fears; check to the over-bold;
Nurse, whose calm hand its strong restriction lays,
Kind but resistless, on our wayward days;
Mart, where high wisdom at vast price is sold;

Gardener, whose touch bids the rose-petals fall,
The thorns endure; surgeon, who human hearts
Searchest with probes, though the death-touch be given;
Spell that knits friends, but yearning lovers parts;
Tyrant relentless o'er our blisses all; —
Oh, can it be, thine other name is Heaven?
