Early [original enlightenment or hongaku shiso period] writing of Nichiren [1258]

"This Myoho-renge-kyo is a term designating the essential nature of our minds, or, more generally speaking, the essential nature of the minds of all living beings, the eight-petaled white lotus blossom. The words of the Buddha himself teach us this. From time without beginning until the present, these bodies of ours have transmigrated through the realm of birth and death, in a state of delusion as to the essential nature of the mind that is within these bodies. But now that we have encountered the Lotus Sutra and chant the daimoku that represents the Thus Come One of original enlightenment, who possesses the three bodies in a single body, the Thus Come One becomes manifest. In our present existence we achieve the inner realization and attainment of Buddhahood that is known as the attainment of Buddhahood in our present form."
