As a Nichiren Buddhist , the lotus flower is a very powerful symbol. "Renge" means lotus flower. The lotus blooms and produces seeds at the same time, and thus represents the simultaneity of cause and effect. The circumstances and quality of our individual lives are determined by the causes and effects, both good and bad, that we accumulate (through our thoughts, words and actions) at each moment. This is called our "karma." The law of cause and effect explains that we each have personal responsibility for our own destiny. We create our destiny and we can change it. The most powerful cause we can make is to chant Nam-myoho-renge-kyo; the effect of Buddhahood is simultaneously created in the depths of our life and will definitely manifest in time.
