Walt Whitman: Passage to India, Part 4

Passage to India!
Struggles of many a captain, tales of many a sailor dead,
Over my mood stealing and spreading they come,
Like clouds and cloudlets in the unreach'd sky.

Along all history, down the slopes,
As a rivulet running, sinking now, and now again to the surface rising,
A ceaseless thought, a varied train—lo, soul, to thee, thy sight,
they rise,
The plans, the voyages again, the expeditions;
Again Vasco de Gama sails forth,
Again the knowledge gain'd, the mariner's compass,
Lands found and nations born, thou born America,
For purpose vast, man's long probation fill'd,
Thou rondure of the world at last accomplish'd.
