I've just read a couple of passages so beautiful, I have to share them (excerpted from Kahlil Gibran's The Prophet). Gibran's "Prophet" declaims on Love, Giving, Joy, Sorrow, Material Goods, Good and Evil (wow), Relationships (the insight!), Friendship, Death and many other things. With the pinnacle of Clarity. It was difficult to decide what to include, but if you're looking for more, it's only 90 pages.

The Prophet on Self-Knowledge:

"Your hearts know in silence the secrets of the days and the nights.
But your ears thirst for the sound of your heart's knowledge.
You would know in words that which you have always known in thought.
You would touch with your fingers the naked body of your dreams.

And it is well you should.
The hidden well-spring of your soul must rise and run murmuring to the sea;
And the treasure of your infinite depths would be revealed to your eyes.
But let there be no scales to weigh your unknown treasure;
And seek not the depths of your knowledge with staff or sounding line.
For self is a sea boundless and measureless.

Say not, 'I have found the truth,' but rather, 'I have found a truth.'
Say not, 'I have found the path of the soul.' Say rather, 'I have met the soul walking upon my path.'
For the soul walks upon all paths.
The soul walks not upon a line, neither does it grow like a reed.
The soul unfolds itself, like a lotus of countless petals."

The Prophet on Love:

"When love beckons you, follow him,
Though his ways are hard and steep.
And when his wings enfold you yield to him,
Though the sword hidden among his pinions may wound you.
And when he speaks to you believe in him,
Though his voice may shatter your dreams as the north wind lays waste the garden.

For even as love crowns you so shall he crucify you. Even as he is for your growth so is he for your pruning.
Even as he ascends to your height and caresses your tenderest branches that quiver in the sun,
So shall he descend to your roots and shake them in their clinging to the earth.

...

But if in your fear you would seek only love's peace and love's pleasure,
Then it is better for you that you cover your nakedness and pass out of love's threshing-floor,
Into the seasonless world where you shall laugh, but not all of your laughter, and weep, but not all of your tears.

Love gives naught but itself and takes naught but from itself.
Love possesses not nor would it be possessed;
For love is sufficient unto love.

...

Love has no other desire but to fulfill itself.
But if you love and must have desire, let these be your desires:
To melt and be like a running brook that sings its melody to the night.
To know the pain of too much tenderness.
To be wounded by your own understanding of lovel
And to bleed willingly and joyfully.
To wake at dawn with a winged heart and give thanks for another day of loving;
To rest at the noon hour and meditate love's ecstasy;
To return home at eventide with gratitude;
And then to sleep with a prayer for the beloved in your heart and a song of praise upon your lips."
