similarities in culture

this is Lauburu, the Basque Cross. one sees it everywhere in the basque regions. it symbolises the turing of the four seasons.
when i first saw this icon, i thought how familiar it felt to me. then i realized, it's very similar to the chinese symbol of similar meanings.

but while i'm researching, i came across the origin of the word swastika. it's hindu....
.....


The swastika is a type of solar cross, with arms bent at right angles, suggesting a whirling or turning motion. Long before the symbol was co-opted as an emblem of Hitler's Nazi party, it was a sacred symbol to Hindu, Jain, and Buddhist religions, as well as in Norse, Basque, Baltic, and Celtic Paganism.
The name Swastika is derived from the Sanskrit language, from "su," meaning "good," and "vasti"," meaning "being" (together; well being) In India, it is used as a fertility and good luck charm.
The right turning Indian swastika symbolizes the sun and positive energy, and is most commonly associated with the deity Ganesh, a God of prosperity and wealth. Some Indians regard an anti-clockwise swastika as an opposing, dark force- a symbol of the godess Kali. Together, the two can be regarded as symbolically similar to the Yin Yang symbol of Taoism, or the two Pillars of Kabbalah.
....... etc...
and since i was just in thailand, the greeting word is "sawadeeka"
which upon further reading, according to wikipedia, (http://en.wikipedia.org/wiki/Swastika)
it's also related to the swastika (hindi word) for well-being.

all this just reminds me of Joseph Campbell's lectures on cultures and religions.
