Alfred, Lord Tennyson - "Mine be the strength of spirit..." lyrics

Mine be the strength of spirit, full and free, Like some broad river rushing down alone, With the selfsame impulse wherewith he was thrown From his loud fount upon the echoing lea: ­ Which with increasing might doth forward flee By town, and tower, and hill, and cape, and isle, And in the middle of the green salt sea Keeps his blue waters fresh for many a mile. Mine be the Power which ever to its sway Will win the wise at once, and by degrees May into uncongenial spirits flow; Even as the great gulfstream of Florida Floats far away into the Northern Seas The lavish growths of Southern Mexico.
