"The cruelest prisons are those we build for ourselves."

Kate Chopin

Novelist American 1850–1904

"The voice of the sea is seductive, never ceasing, whispering, clamoring, murmuring, inviting the soul to wander in abysses of solitude."

"I would give up the unessential. I would give my money, I would give my life for my children; but I wouldn't give myself."

"A certain light was beginning to dawn dimly within her—the light which, showing the way, forbids it."

"If it is a divine call, no matter how unexpectedly it comes, I should obey it."
