This is his explanation of the swastika.
In the Chinese alphabet, the Swastika in a circle stands for “sun”, and without the circle it means the number 10,000 (in Chinese: wan or Wantzü) which means “come from the heavens”.
1) There is no such thing as a Chinese alphabet. I'm pretty sure everyone here knows that, but the author plainly doesn't.
2) The swastika
is a Chinese
character, but it does not really mean anything other than, well, swastika. It simply symbolises itself as an auspicious character. You normally see it in the word 卍字 (also written 萬字, see 3 below)
wànzì which simply means "swastika symbol".
2) The Chinese character for "sun" is 日. As you can see, it is not a swastika in a circle. My Chinese dictionaries don't include a swastika in a circle at all.
3) The Chinese character for 10,000 is 万 in Simplified and 萬 in Traditional. It is not a swastika, though it does have the same
pronunciation as the swastika character:
wàn.
To me, of course, 卍 is a holy (not quite the right word but I can't think of a better) symbol, one of the thirty-two marks of a Buddha, and its appropriation by the Nazis, and present-day association with the racist extreme right, is most unfortunate. I have very mixed feelings about the adoption of sacred symbols of one culture by another. I hope it is based on deeper cultural knowledge and understanding than that demonstrated by the linked article I quote above.
