I suspect the file simply does not exist. Sometimes things can be a bit random at a monastery; we don’t approach these things in a very professional way. Usually one of the monks just decides to record the talks and then it sort of happens if that monk is present. I am sure you get the idea! (Actually, this is one of the charms of monastic life, that we don’t take these worldly things very seriously. It make for a less fault-finding and light-hearted life.)
As for the quality of the talks, please remember that these were done with an in-house audience in mind. Many of the things said are no doubt inappropriate and politically incorrect. Please don’t get too hung up on this. If anyone is offended, I apologise right now.
