In the “Record of the Orally Transmitted Teachings,” Nichiren says, “One should regard meeting obstacles as true peace and comfort” (Gosho Zenshu, p. 750). You may wonder how encountering obstacles could be a source of peace and comfort. But the truth of the matter is that through struggling against and overcoming difficulties, we can transform our destiny and attain Buddhahood. Confronting adversity, therefore, represents peace and comfort.
