The lotus flower represents one symbol of fortune in Buddhism. It grows in muddy water, and it is this environment that gives forth the flower’s first and most literal meaning: rising and blooming above the murk to achieve enlightenment.
The second meaning, which is related to the first is purification. It resembles the purifying of the spirit which is born into murkiness.
The third meaning refers to faithfulness. Those who are working to rise above the muddy waters will need to be faithful followers.
