Yes, I am actually a practitioner of Nichiren Buddhism. He was a 13th century Buddhist reformer who determined that the Lotus Sutra was the highest teaching of Shakyamuni Buddha (a.k.a. Siddhartha). He developed the practice of chanting "nam myoho renge kyo" which means "I dedicate my life to the mystic law of cause and effect through sound and vibration." I chant this every day and I have found that it has changed my life in many amazing ways.
