Soka Gakkai is a lay-based, modern Nichiren practice that originated in Japan in the 1930s. It is based on the teachings of Nichiren Buddhism, which was founded by the 13th-century Japanese monk, Nichiren. The main teachings of Soka Gakkai revolve around the concept of human revolution, the power of the Law, and the importance of faith, practice, and study.

Human Revolution is a core teaching of Soka Gakkai, which emphasizes the transformation of the individual through self-reflection and inner growth. It teaches that by changing oneself, one can positively impact the world and create a better society. This concept is based on the belief that all individuals have the potential to achieve enlightenment and that by engaging in a continuous process of self-improvement, one can tap into their inner wisdom and compassion.

The power of the Law is another important teaching in Soka Gakkai. It refers to the universal law of cause and effect, also known as karma. According to this teaching, every action we take, whether positive or negative, will have a corresponding effect on our lives. Therefore, by making positive causes, such as chanting and engaging in compassionate actions, we can create positive effects in our lives.

Faith, practice, and study are also essential teachings in Soka Gakkai. The practice of chanting Nam-myoho-renge-kyo, the title of the Lotus Sutra, is considered the core of this faith. It is believed that by chanting, one can tap into their innate Buddha nature and awaken to their true potential. Along with chanting, Soka Gakkai encourages its members to engage in daily Buddhist practice, such as reciting sutras, studying Buddhist teachings, and participating in activities to promote peace and social justice.

Soka Gakkai also emphasizes the importance of studying Buddhism. It encourages its members to deepen their understanding of Nichiren's teachings and to apply them in their daily lives. Through study, one can gain a better understanding of the principles of Buddhism and how to apply them to overcome life's challenges and achieve personal growth.

In conclusion, the main teachings of Soka Gakkai revolve around the concept of human revolution, the power of the Law, and the importance of faith, practice, and study. These teachings aim to empower individuals to take responsibility for their own happiness and to contribute to the betterment of society. By following these teachings, Soka Gakkai members strive to create a more peaceful and harmonious world for all.
