Haste her to the Purpose.

IF thought can reach to Heaven,
On Heaven let it dwell,
For fear that Thought be given
Like power to reach to Hell.
For fear the desolation
And darkness of thy mind,
Perplex an habitation
Which thou hast left behind.

Let nothing linger after--
No whispering ghost remain,
In wall, or beam, or rafter,
Of any hate or pain:
Cleanse and call home thy spirit,
Deny her leave to cast,
On aught thy heirs inherit,
The shadow of her past.

[ The Rabbi's Song, Rudyard Kipling ]
