Difficult to know what to make of it all. Is anyone instructing him? Has he become a Catholic, or is he attached to some denomination? Or is this just a feelgood 'spirituality' thing? I saw a video of him praying (he called it 'chanting') the rosary, and then very recently another video of him dabbling with tarot cards. He needs a good priest to give him instruction. I hope and pray he finds one.
@Maggie212 You're right about the Thames. I wouldn't let a dog in it. There have been cases of Weil's disease (leptospirosis) carried by small river rodents
