The lotus flower is considered the most sacred of flowers in Buddhism and where tradition says it is symbolically where Buddha was born.
We must pay close attention where Buddha is sitting, as it usually does on a lotus flower. The lotus flower means spiritual purity, or the purity of body and soul. Legend has it that when Buddha was a child, where trod bloomed lotus flowers. The muddy waters from which they spring means attachments in life and carnal desires but its flower above those waters means the pursuit of light and spiritual elevation. There are different colors in the Lotus flower, but the most important is precisely the rose, like the image.
