The current format has evolved over the years. Originally, it followed the format of Nichiren Shoshu. In the 1970s, silent prayers were added for the success of the Soka Gakkai itself, and in memory of its first two deceased presidents, in addition to prayers for Nichiren and his disciple Nikko. Currently, after the recitation of the 2nd chapter and the verse section of the 16th chapter, daimoku is chanted for as long as desired, after which all the silent prayers are recited to conclude gongyo. The SGI's version of sutra recitation takes approximately 5 minutes, leaving more time for the primary practice of chanting Nam-myoho-renge-kyo. As of 2015, the silent prayers currently are: gratitude to the Gohonzon, to Nichiren, and to his immediate successor Nikko; appreciation for the three founding presidents of the organization; a prayer for the fulfillment of the great vow for worldwide kosen-rufu, for the human revolution and attainment of goals of the practitioner, and for the deceased; and finally for the happiness of all living beings. It is emphasized by the Soka Gakkai, however, that more important than the wording of the prayers is the practitioner's heartfelt intent in doing gongyo and expressing his or her appreciation and desires.
