In Buddhism, the swastika signifies auspiciousness and good fortune as well as the Buddha's footprints and the Buddha's heart. The swastika is said to contain the whole mind of the Buddha and can often be found imprinted on the chest, feet or palms of Buddha images. It is also the first of the 65 auspicious symbols on the footprint of the Buddha.
The swastika has also often been used to mark the beginning of Buddhist texts. In China and Japan, the Buddhist swastika was seen as a symbol of plurality, eternity, abundance, prosperity and long life.
The swastika is used as an auspicious mark on Buddhist temples and is especially common in Korea. It can often be seen on the decorative borders around paintings, altar cloths and banners. In Tibetan Buddhism, it is also used as a clothing decoration.
