It's been years since I've read Paz, and his poetry is just as strong as I remember.
In fact I'm going to go out on a limb and say that no modern poet with the possible exception of Allen Ginsburg has such a rich and powerful sense of description as Paz. The opening poem 'Mutra' especially, is just a gorgeous overflow of reveries, symbols and perceptual shifts. It alone makes this book worth buying.
Paz's repertoire of images is unbeatable precisely because of how elemental it is. The sun, the moon, water, stones, darkness, sunlight...he constantly returns to these primordial sensations and always manages to make them feel vital and lived in, no matter how often he uses them. I highly recommend this, or really any of his collections of poetry.
