It's a pretty good book about a prophet who leaves the island he's been living on for more than 10 years. But before he discusses topics with the citizens like what is life, love or pain. It consists of small, independent chapters so you can just read one or two if you dont have much time.

“The timeless in you is aware of life's timelessness. And knows that yesterday is but today's memory and tomorrow is today's dream.”

“Let there be spaces in your togetherness, And let the winds of the heavens dance between you. Love one another but make not a bond of love: Let it rather be a moving sea between the shores of your souls. Fill each other's cup but drink not from one cup. Give one another of your bread but eat not from the same loaf. Sing and dance together and be joyous, but let each one of you be alone, Even as the strings of a lute are alone though they quiver with the same music. Give your hearts, but not into each other's keeping. For only the hand of Life can contain your hearts. And stand together, yet not too near together: For the pillars of the temple stand apart, And the oak tree and the cypress grow not in each other's shadow.”

“Some of you say, “Joy is greater than sorrow,” and others say, “Nay, sorrow is the greater.” But I say unto you, they are inseparable. Together they come, and when one sits alone with you at your board, remember that the other is asleep upon your bed.”

“You give but little when you give of your possessions.
It is when you give of yourself that you truly give.”

“Beauty is eternity gazing at itself in a mirror.
But you are eternity and you are the mirror.”

“You talk when you cease to be at peace with your thoughts.”
