Akkadian expression of the day:
Pirištu ša ilāni rabûti ("the secret of the great gods").

Pictured: the Tōkyō branch temple of Kōyasan (高野山東京別院, Kōyasan Tōkyō Betsuin), representing the Shingon school of esoteric/Vajrayāna Buddhism - the one with all the secret mudrās - secret hand gestures - and mantras). I woujld very much like to visit the main Kōyasan temple, which is, well, on Mount Kōya in Wakayama Prefecture. Maybe one day!
