In Buddhism, the practice was adapted to express veneration of the Buddha as universal sovereign. The eight symbols are often placed before images of the Buddha. They are: parasol (power and protection); two fish (kingship); conch shell (conqueror); lotus blossom (purity); water-jar (nectar of amṛta); banner (victory of the spirit); knot (endless eternity); wheel of teaching (dharma-cakra).
