The Cat's Eye Stone: A Light Hidden in the Pupil

In the ancient legends of China and Southeast Asia, the cat's-eye stone was a gem touched by the divine. People believed that cats could see things in the dark that human eyes could not, and that this very light hid within their pupils. According to the tale, an old cat who had spent a thousand years in quiet cultivation, on the eve of its passing, left that light behind in the human world. It took the form of a slender band of glow within the stone — a pupil that opens and closes with the light. Travelers once carried it as a charm against dangers lurking in the dark. Today, scientists have long explained its mineral origins, yet the legend of the old cat still travels from mouth to mouth.
