Soka Gakkai, a lay-based modern Nichiren practice, does have specific rituals and ceremonies that are an integral part of its practice. These rituals and ceremonies serve as important tools for members to deepen their faith and strengthen their connection with the teachings of Nichiren Buddhism.

One of the most significant rituals in Soka Gakkai is Gongyo, which literally means "assiduous practice." It is a daily recitation of two chapters from the Lotus Sutra, the central scripture of Nichiren Buddhism. Gongyo is usually performed in the morning and evening, and it is believed to help individuals align their lives with the principles of the Lotus Sutra and awaken their inherent Buddha nature.

Another important ceremony in Soka Gakkai is the monthly discussion meeting. These meetings are held at local community centers or members' homes and provide an opportunity for members to gather and share their experiences and insights on the practice. The monthly discussion meeting also includes chanting Nam-myoho-renge-kyo, a central mantra in Nichiren Buddhism, and studying the writings of Nichiren and the Soka Gakkai founder, Tsunesaburo Makiguchi.

In addition to these regular rituals and ceremonies, Soka Gakkai also holds special ceremonies to commemorate significant events in the Buddhist calendar, such as the anniversary of Nichiren's birth and the Soka Gakkai's founding day. These ceremonies often include recitation of the Lotus Sutra, chanting, and studying the teachings of Nichiren.

Soka Gakkai also has a specific ritual for individuals who are going through challenging times or facing obstacles in their lives. This ritual is called "Shodaigyo," which means "chanting for the fulfillment of one's wishes." Members chant Nam-myoho-renge-kyo with a specific goal or wish in mind, believing that the power of this mantra can help them overcome their difficulties and achieve their goals.

Furthermore, Soka Gakkai also has specific rituals and ceremonies for significant life events, such as weddings, funerals, and memorial services. These ceremonies incorporate Buddhist teachings and practices to honor and celebrate these important milestones in a person's life.

In conclusion, Soka Gakkai has various rituals and ceremonies that play a crucial role in its practice. These rituals and ceremonies serve as powerful tools for members to deepen their understanding of Nichiren Buddhism and strengthen their faith in the teachings. They also provide a sense of community and support for members to navigate through life's challenges and celebrate its joys.
