Tonight, I went to a local park and did and LBRP and middle pillar while holding two coins. I said a little prayer to the boatman asking him to transport my grandmother and with care. I dropped the energy into the coins and tossed them into the lake. They sailed poetically over a fallen tree. I believe that was the first time, besides goetic work, where I felt an entity accept an offering.
I never knew the boatman had a name but I left feeling as if I should know it. A little research shows at least one of his names is Charon.
