"The Vision" (1994) is a collection of Gibran's spiritual writings published well after his death. It has its moments but it's uneven and a big step down from "The Prophet" (1923).

Quotes:
On brotherhood and nationalism, from "The Voice of the Poet":
"Human beings separate into factions and tribes and adhere to countries and regions whereas I see my essence as foreign to any one land and alien to any single people. The entire earth is my homeland and the human family is my clan."
...
"I crave my homeland for its beauty and love its inhabitants for their poverty. Yet when my people set out to defend what they call nationalism and march upon the homeland of my neighbors - plundering their wealth, killing their men, making orphans of their children, and widows of their women, spilling the blood of their sons on the earth, and feeding the flesh of their youth to beasts of prey - then I hate my country and its inhabitants."

On wisdom, from "The Visit of Wisdom":
"She said, 'You desire, O mortal, to view this world through the eyes of a god, and wish to comprehend the mysteries of the world to come by means of your human intellect; and this is the utmost folly. Go out into the open country, and you will find the bee hovering over flowers and the eagle picking apart its prey. Enter the house of your neighbor, and you will see a child bedazzled by the fire's rays, while the mother busies herself with housework. Imitate the bee and do not spend the days of spring gazing upon the deeds of the eagle. Be as the child and delight in the flame's brightness, and pay no heed to your mother and her affairs."

On wisdom, from "Flower Song":
"I drink the wine of dew, listen to the songs of thrushes, and dance to the applause of hte grasses. I ever look upward, that I might see the light rather than my own fantasies, and this is a wisdom that humans have not yet learned." ( )
