Tell me what that means to you, Supriyo. I'm a communicator and I don't know what it's communicating. How does a glacier knock a cupboard and why would it? I can understand all of Van Dyke Park's lyrics in the Beach Boy's "Surf's Up" song than I do in those four lines, but that song's melody gives it more creative credence. I couldn't hear most of Park's lyrics and had to read them online. Also I don't read poems. Not my medium of communication for obvious reasons. What I see of poetry writing is pretty much word scatting like jazz improvisational singers except the words used usually have no connection to any ideas or emotions because words project a literal meaning where musical sound is more soulful. And there isn't enough data to prove EVERYONE knows of Octavio Paz.
