📿 About the Heart Sutra
The Heart Sutra is one of Japan’s most beloved Buddhist texts.
Its 262 characters¹ distill the vast teachings of the Mahayana classic Prajñāpāramitā (over 600 volumes) into a single, resonant chant.
Translated from Sanskrit into Chinese by Xuanzang in the 7th century, the sutra’s final mantra—“Gate Gate…”—is a phonetic transcription of sacred sounds, adding to its mystical allure.
For centuries, it has offered quiet prayer and profound insight to countless hearts.
This watch face gently brings that spirit into your smart, modern life.
