Reading Borges today, I'm only getting a fleeting glimpse at a possible genius because it is so intense. I think it might take a while to get to grips with it. I keep thinking I will understand it some day but then I think maybe its not meant to be understood. He always writes from the first person and he makes you think that maybe the narrator is tricking you. For example this neat little part from the introduction of 'The Lottery in Babylon':
Look: through the rip in my cape you can see a vermillion tattoo on my stomach. It is the second symbol, Beth. This letter on nights when the moon is full, gives me power over men whose mark is Gimmel, but it subordinates me to the men of Aleph, who on moonless nights owe obedience to those marked with Gimmel.
