For washed in life's river, My bright mane forever Shall shine like the gold As Iguard o'er the fold. - William Blake

Why art thou silent and invisible,
Father of Jealousy?

And we are put on earth a little space,
that we may learn to bear the beams of love;
And these black bodies and this sunburnt face
Is but a cloud, and like a shady grove.

Those who restrain desire, do so because theirs is weak enough to be restrained; and the restrainer or reason usurps its place & governs the unwilling.
And being restrain'd it by degrees becomes passive till it is only the shadow of desire.
