If an eagle gives you a feather, keep it safe.
Remember: that giants sleep too soundly; that
witches are often betrayed by their appetites;
dragons have one soft spot, somewhere, always;
hearts can be well-hidden,
and you betray them with your tongue.

Do not be jealous of your sister.
Know that diamonds and roses
are as uncomfortable when they tumble from one's lips as toads and frogs:
colder, too, and sharper, and they cut.

Remember your name.
Do not lose hope -- what you seek will be found.
Trust ghosts. Trust those that you have helped to help you in their turn.
Trust dreams.
Trust your heart, and trust your story.

When you come back, return the way you came.
Favors will be returned, debts be repaid.

Do not forget your manners.
Do not look back.
Ride the wise eagle (you shall not fall).
Ride the silver fish (you will not drown).
Ride the grey wolf (hold tightly to his fur).

There is a worm at the heart of the tower; that is why it will not stand.

When you reach the little house, the place your journey started,
you will recognize it, although it will seem much smaller than you remember.
Walk up the path, and through the garden gate you never saw before but once.
And then go home. Or make a home.

Or rest.

Neil Gaiman
