Astamangala means "eight auspicious signs". It refers to the Eight Buddhist Treasures, a suite of eight auspicious symbols relating to Buddhism. They often feature in the arts of Buddhist cultures, including sword mounts.
The classic eight, commonly encountered on Tibetan and Chinese art, are:
Wheel of dharma
Represents Gautama Buddha and the Dharma teaching.
Symbolizes love and the intertwined unity of everything.
Refers to the Buddha's teaching spreading in all directions like the sound of the conch trumpet, awakening his subjects from the deep slumber of ignorance.
The symbol represents the Buddha's victory over the four hindrances in the path of enlightenment; pride, desire, disturbing emotions, and the fear of death.
Emerging from the murky, muddy depths, growing towards the light and producing a pristinely white flower above the surface, lotus symbolizes the path towards enlightenment.
Pair of fish
Symbolizes moving freely and spontaneously, without fear of drowning in the ocean of suffering.
Symbolizes long life, wealth and prosperity.
A symbol of protection from the suffering experienced in the lower realms of existence.
Numerous variations to this list exist. Nepali Buddhists, for example, replace the wheel of dharma for a fly whisk. A Yuan dynasty dish, one of the earliest depictions of the suit known to me, replace the parasol for a pair of rhino tusks. This symbol is more often encountered in a different set, the Eight Auspicious Symbols.
