Traditional Thank-you Card by Buddhist Priest

At MIYASHIRO, the Shinto Shrine, the first religious building constructed at GARAN, on Koyasan where enshrines NYUTSUHIME and KARIBAMYOJIN, they have 2 wooden stands. One stands to hold EMA, a votive picture tablet for Shinto Shrine and the other (which is not commonly seen any other places but Koyasan) stands to nail the wooden tablets by Buddhist priests. Of course, those wooden tablets work as votive picture tablets for Buddhist prosperity but they rather work as a kind of thank-you cards. It is one of custom for Koyasan priests who coompleted their hard practice period, they make themselves these wooden tablet and visit their local KAMI, Shinto Deities to appreciate for their successful completion. They are also offered to their masters' temples as well as their parents. So Buddhist priests write themselves and show their sincerest thanks to KAMI and people who support them.
Today, I saw a young priest nailing his tablet to MIYASHIRO, sincerely offered his chanting to KAMI and left Koyasan.
