Teacher Jiang Xun said that Barong Temple's smile was like a Diamond Sutra. At first, I didn't understand what it meant. Khmer's smile, in that war-torn era, the age of hunger, the age of blood flowing into rivers, people more cruel than beasts to kill each other, he has been so quiet smile. Is this smile so hard to understand, because of what you see and understand, or because you don't look at anything and don't want to understand? Beauty may always be between solvable and insoluble. Solvable is rational, logical and scientific. Unsolvable is mysterious and religious. The text of Diamond Sutra is difficult to understand. The smile of Barong Temple is a Diamond Sutra.
