In Buddhism, one of 8 Auspicious Symbols, lotus flowers mean purity of speech, mind & body rising above the waters of desire & attachment. 4 colors symbolically represent different aspects of perfection (pink, blue, red, white). Red represents the heart-its purity, original nature, compassion, passion, love & other qualities. White symbolizes spiritual perfection & complete mental purity. Pink represents the Buddha & is the supreme lotus. Blue means wisdom, knowledge & victory over the senses.
