Because the topic of my posts on the Shobogenzo has been a subject of discussion elsewhere, I thought it might be of benefit, if not exactly enlightening, to post a copy of the original email granting permission. I recently found a print-out of the email, though the email account itself was deleted before I left for Antai-ji. I took the email at face value.
One of the reasons I post it now is that it speaks to how remarkably easy it is for our perceptions to get distorted by the impressions and conjectures of people who are reacting to things they know very little about. I don't think any of us are immune, myself included.
