 The coming together of water and stone is symbolic of the yin-yang in numerous locations throughout the San Francisco Japanese Tea Garden, as seen in the waterfalls, water basins made of stone, flat stones across the ponds, and waves in the stones of the dry Zen Garden.The aesthetics of the garden are further influenced by the principle of concealment, which involves messages that come in pieces to ultimately reveal a larger picture.For example, the dragon hedge of the Japanese Tea Garden only reveals itself as a dragon after being followed from tail to head.
