This photo was taken at the Wisdom Path at Lantau Island.
This is part of the wood inscription of the "Prajna Paramita Hrdaya Sutra" (Heart Sutra) erected at a slope at the Lantau Peak. The wood craving was the calligraphy of Professor Jao Tsung-I.
The Chinese characters mean "A heart without worry or obstacle" - another version of "Live Water"?
