Describe symbolism in Letters to a Young Poet by Rainer Maria Rilke

Rilke does not use symbolism, per se. He does, however, write the first and last letters from Paris. This fact has two completely different symbolic values. The first is as a manifestation of Paris being, as it were, the beginning and the end of artistic expression at the time the letters were written. The second, and perhaps more relevant, is that at the point of the first and last letters, the Young Poet is at both the end of an old journey and the beginning of a new one—the end of an old experience of being, the beginning of a new, exciting, enticing, way of seeing, feeling and creating.
