Three possible readings of Kafka's The Castle

Possible "meanings" of Frank Kafka's "The Castle" include (list could go on forever): It's about an Oedipal struggle. We all know of Kafka's legendary difficulties with his father, and he plays out these themes in this strange novel, with the protagonist, K., seeking to get an interview with a powerful male figure (Klamm) whom he observes only in occasional glimpses: a powerful man with a dark mustache sitting at a desk, drinking from a glass of beer. K.s mother-in-law (to be) has been the mistress of this Klamm, and he sees his mother-in-law as a very large figure, slouching on a bed in the dark - like a child's view of his mother perhaps, but mixed with sexual yearnings. So the novel is about this need for recognition by the father and to escape from the dominance of the mother. Also, Klamm is a "silent god" figure whom all revere but whom few knew or have seen, who controls all but gives nothing. K. has, about half-way through the book, received a letter from Klamm praising him (and his idiotic assistants) for their good work, and this deeply upsets K., in that he has done no work yet. He asks the totally ineffective messenger, Barnabus, to get a message to Klamm, but it's obvious that Barnabus can't do this. So there's another "reading," The Castle as an allegory of our incapacity to understand the ways of god to men. Another possibility: is The Castle actually about the act or, or art of, reading and interpretation, one of the first postmodern novels? The closer you get to perceiving the meaning of the novel, the more it recedes - much like K.'s approach to but inability to actually perceive the castle, just above the village but always hidden in mist and fog.
