Follow your inner moonlight; don’t hide the madness.
No excellent soul is exempt from a mixture of madness
O! that way madness lies; let me shun that.
‘But I don’t want to go among mad people,’ said Alice. ‘Oh, you can’t help that,’ said the cat. ‘We’re all mad here.’

Madness need not be all breakdown. It may also be break-through. It is potential liberation and renewal as well as enslavement and existential death
A breath of wind from the wings of madness
Love is merely madness...
Anybody remotely interesting is mad, in some way or another.
