How about The Patthana?
From the Atthasalini (Translated as the Expositor):
"...The Elder Mahagatigamiyatissa crossed over to the opposite shore of India with the intention of paying homage to the Wisdom Tree. Seated on the upper deck of the boat he looked at the great ocean; but neither the thither nor the hither shore appeared to his vision. There appeared only the great ocean, strewn with foam thrown off by the breaking of the billows, and looking like a sheet of silver spread out on a bed of jasmine flowers. He thought to himself: Which is more extraordinary - the heaving of the ocean waves, or the basis of the method of the twenty-four divisions in the Great Book? Then the limits of the great ocean became apparent to him. Indeed, he thought to himself: This ocean is limited, below by the earth, above by the sky, on one side by the mountain encircling the world system, and on the other by the seashore. But the limits of the universal Pa.t.thaana are not apparent. And abundant rapture arose in him, as he reflected on the subtle and abstruse Law. Arresting his rapture and increasing his insight even while he was seated, he threw off all the corruptions, and being established in the topmost Fruition which is Arahantship, he exulted in this song of ecstasy:
He is the true disciple of the Sage
Who sees, like a bright jewel in his hand,
Root-causes, from which all becoming is -
Lore deep and hard to know, which the Great Sage
Intuited, and all in order taught."
