The yin yang is one of the oldest symbols of balance, holding the idea that opposing forces are partners rather than enemies: light needs dark, stillness needs movement, rest needs effort.
Here the philosophy is rendered literally. Black sand and white sand meet along the same curved boundary found in the traditional symbol, and each half holds a single stone in the opposite shade, echoing the seed of one that lives within the other.
The piece also draws on Japanese karesansui design, where miniature sand gardens have long been used for contemplative practice. Raking becomes a small meditation on balance itself, a way of shaping order out of the two halves without erasing either one.
