There is a kind of lotus, ice lotus. Two flowers bloom on a branch at the same time, just like inseparable lovers. Moreover, lotus grows out of mud, but it will not be defiled, and its color is still pure, giving people a sense of loyalty and beauty.
Noble and holy lotus has always been regarded as a sacred and clean flower by Buddhism, and it is strongly advocated to learn from this innocent and holy spirit of lotus.
Zhou Dunyi's idea of "emerging from the mud without dyeing, wrapping violets without demons" has given the lotus an elegant fashion. The lotus flowers written by literati in past dynasties are all natural, pollution-free and innocent images.
