The Original Eternal Shakyamuni Buddha is eternally endowed with the three bodies

‘Single-mindedly desiring to see the Buddha’ also means to see the Buddha in one’s own mind, to concentrate one’s mind on seeing the Buddha, and that to see one’s own mind is to see the Buddha. I have attained the fruit of Buddhahood, the eternally inherent three bodies, 4 [by living this sentence]. In achieving this I am sure I surpass T’ien-t’ai and Dengyo, Nagarjuna and Mahakashyapa. The Buddha admonishes that one should by all means become the master of one’s mind rather than let one’s mind master oneself. This is why I have emphatically urged you not to hesitate to give up your body and your life for the sake of the Lotus Sutra. Namu-myoho-renge-kyo, Namu-myoho-renge-kyo.

4. Three enlightened properties of life: Here means that Nichiren Daishonin is manifesting the original Shakyamuni Buddha eternally endowed with the three properties-the truth of a Buddha's life (hosshin), the wisdom to perceive that truth (hoshin) and the merciful actions of a Buddha to save the people (ojin). "The three enlightened properties" of the original Shakyamuni Buddha are defined as musa (literally "not created"), a Buddhist term meaning "natural" or "eternally inherent."
