How does the author use imagery in the book, The Motorcycle Diaries: Notes on a Latin American Journey?

Example of Imagery:

"And I see, as if a great exhaustion smothers this fresh exaltation, I see myself, immolated in the genuine revolution, the great equalizer of individual will, proclaiming the ultimate mea culpa. I feel my nostrils dilate, savoring the acrid smell of gunpowder and blood, the enemy's death; I steel my body, ready to do battle, and prepare myself to be a sacred space within which the bestial howl of the triumphant proletariat can resound with new energy and new hope."
