Most Imperial Chinese literati believed that rocks are the bones of the earth and that the essence of the energy of the heaven-earth world coalesces into rock. That energy can be seen in the folds and movement of the upper half of this water-worn rock from Guangxi province. The lower smoother half provides a stable foundation for the churning energy above. Some may refer to this rock as a Ma’an stone; however, it is synonymous with the better known Caitao stone. It originates in the Liuzhou region of Gunagxi province. This block-shaped stone is 25 cm wide, 18 cm high and 18 cm deep and is in the collection of Tom Elias and Hiromi Nakaoji.
