"Rare": the transformation body (nirmāṇakāya). This is because of the four kinds of matters spoken of previously. The intention is to clarify that upholding, reading, and reciting fully obtains the complete merit of the three bodies. Some say: being able to tend toward bodhi, it is called 'most supreme'; surpassing all vehicles, it is called 'foremost'; being incomparable in the world, it is called 'rare.'"},Objectively speaking: "有佛" is having the Buddha.
