I love you as certain dark things are to be loved,
in secret, between the shadow and the soul.
(Pablo Neruda, Sonnet XVII)
Secrecy is often (possibly too often) aligned with shame. But, as Neruda says, certain dark things are to be loved in secret — without shame, and without betraying the secret.
(Pablo Neruda, Sonnet XVII (100 Love Sonnets, 1960))
