This is a
four-sided two page Heart Sutra version used in the early sixties at Sokoji. Later they changed to a two-sided one page version which is what was being used when I arrived in 66. It was fine and didn't seem crowed. Oh I see on the bottom of the card it says "For the memory of Shinsanshiki - Zen Center." That's the ceremony in the spring of 1962 when Shunryu Suzuki officially became abbot. We call it the Mountain Seat Ceremony where Suzuki stepped up to the mountain seat, to be abbot.
