In Hawaii, the chants and movements associated with the hula dance are said to bring good luck. In Tibet, the traditional greeting, "tashi delek," means good luck.
Various cultures all convey good luck in different ways, but Hawaii and Tibet are two of the most notable.
The good luck that hula dancing is said to generate comes from the Hawaiian goddess Laka. Laka is a goddess of love and greenery, hence why hula involves the offering of forest plants.
"Tashi delek" is an expansive good luck evocation that supports people's health, prosperity and goodness. The individual who says "tashi delek" is wishing for the good fortune of someone else.
