Petzold, Buddhist Prophet Nichiren , p 37-38The style of writing the Sacred Title is also significant. On the Mandala, where it occupies the center, and wherever it is used by the Nichiren people, such as on tombstones, banners or books, always the characters forming the Title show curly and projecting strokes, symbolizing radiant rays emitted by it. Here once more we meet a similarity — although admittedly only a formal similarity — with the Nembutsu cult, where the portrait of Amida is usually shown with rays emitting from his body. Nichiren originated this style of writing the Sacred Title, it seems, to convey to the five characters the same divine holiness which Nembutsu worshippers conveyed to the likeness of Amida.
At the same time, obvious Tantric reminiscences are interwoven in the repetition of the Title. The utterance of the Title, similar to a Tantric incantation or mantra, releases the secret powers involved in word and name, and brings into effect the original connection existing between word and name and the creative energies of the universe. According to the Tantric view, there is a magic power in the formulas spoken by the priest during his performance of religious rites. This view, in fact, is not confined to the Tantric Sects, but in a lesser degree is shared by almost all sects of Mahāyāna, as the dhārāṇi used by them, show. The Hoke-kyō itself contains a whole “Dhārāṇi Chapter.” No wonder, then, that Nichiren attached such importance to the recitation of the Title!
