For the Buddhists the lotus flower was a very important symbol. the lotus flower grew in muddy and murky waters, the meaning of the lotus flower, was to rise above all of the mud and murk to achieve enlightenment,
the Buddhists Lotus flower symbol had three meanings. the first one was the one above, the second one represents purifying your life which is born in murkiness. the last meaning is: “The third meaning refers to faithfulness. Those who are working to rise above the muddy waters will need to be faithful followers.” http://buddhists.org/buddhist-symbols/the-meaning-of-the-lotus-flower-in-buddhism/
I think that the lotus flower is a very good symbol and it fits the Buddhists very well.
