Context: But he, though blind of sight,
Despised, and thought extinguished quite,
With inward eyes illuminated,
His fiery virtue roused
From under ashes into sudden flame,
[... ]
So Virtue, given for lost,
Depressed and overthrown, as seemed,
Like that self-begotten bird
In the Arabian woods embost,
That no second knows nor third,
And lay erewhile a holocaust,
From out her ashy womb now teemed,
Revives, reflourishes, then vigorous most
When most unactive deemed;
And, though her body die, her fame survives,
A secular bird, ages of lives.

Context: One who is in a dying condition is regarded as a living person in all respects. It is not permitted to bind his jaws, to stop up the organs of the lower extremities, or to place metallic or cooling vessels upon his navel in order to prevent swelling. He is not to be rubbed or washed, nor is sand or salt to be put upon him until he expires. He who touches him is guilty of shedding blood. To what may he be compared? To a flickering flame, which is extinguished as soon as one touches it. Whoever closes the eyes of the dying while the soul is about to depart is shedding blood. One should wait a while; perhaps he is only in a swoon.
