It's a outdoor replica of the centuries old Heart Sutra - one of the worlds best known prayers that is revered by confucians, buddhists and taoists alike. The Sutra is on wooden pillars which are in a figure of 8 meaning infinity and imeasurable splendour. 1 free pillar at the highest point represents emptiness - which in a nutshell is; when we accept that there are other points of view- we are truely wise.
