"Spirits, when they please, Can either sex assume, or both; so soft And uncompounded is their essence pure, Not tied or manacled with joint or limb, Nor founded on the brittle strength of bones, Like cumbrous flesh; but, in what shape they choose, Dilated or condensed, bright or obscure, Can execute their aery purposes, And works of love or enmity fulfil." Milton.
