Why do we need to study the writings of Nichiren Daishonin and the guidance of SGI president Ikeda?

Nichiren Daishonin taught, “Exert yourself in the two ways of practice and study. Without practice and study, there can be no Buddhism.” (WND vol 1, pg386) The “study” here refers to the study of Nichiren Daishonin’s Buddhism.
We named the works of Nichiren Daishonin, his theses, auto-biography, letters to his followers, remonstrations all grouped to name them Gosho (Writings of Nichiren Daishonin). From the standpoint of the Buddha in the Latter Day, in order to open the path for the people of the Latter Day to attain enlightenment, the Daishonin had written many goshos. From the starting point to re-establish the basic principles of Buddhism, interpretations on the profound scriptures and teachings and the practical ways to practice this Buddhism through his letters of encouragements to his disciples.
To us, the writings of the Daishonin are the directions for the common people of the Latter Day to attain enlightenment. Therefore, our studies are based all on the writings of Nichiren Daishonin.
The Soka Gakkai (literally, “Society for the Creation of Value”) is the only organization that correctly embrace the spirit of Nichiren Buddhism in the contemporary time, basing on this Buddhist practice and advances to the widespread propagation of the Mystic Law. Through the endeavors of the 3 presidents, we practice in accordance to the teachings of the Daishonin and propagated the Mystic Law to 192 countries and regions worldwide. Through the understanding and practice of the 3 presidents on the writings of the Daishonin, they give guidance with the vision and spirit of the present day; which serves the best way for us to learn Buddhism correctly.
Mr Ikeda and his mentor, 2md president of Soka Gakkai Mr Josei Toda, had studied Buddhism together. They succeeded to the teachings and the spirit of Nichiren’s Buddhism. They have strived through hardships and proofed the correctness of Nichiren’s Buddhism. Mr Ikeda’s constant exchanges with world eminent leaders have established an extensive view of the world. Therefore, the guidance of Mr Ikeda is not only advance, also applicable to anywhere in the world.
More importantly, the guidance of Mr Ikeda is inspiring and filled with encouragement; so that as members, we are able to revital ourselves with new life-force through the study of Mr Ikeda’s works.
