This is Kawaguchi Hidetoshi. This is my humble answer to the question.
Buddha Buddha, Amida Nyorai, Dainichi Nyorai, Yakushi Nyorai...
There are many Buddhas, and furthermore, there are also Kannon Bosatsu, Monju Bosatsu, Fugen Bosatsu... or Fudo Myoo, Aizen Myoo... and Bosatsu, and Myoo, who are being practiced with the aim of enlightenment and have been taught about sentient beings under the guidance of Buddha.
There are certainly so many Buddhas, and I can really understand the feeling that they don't understand what's what.
Actually, the world we are in now is only one of the ridiculously large three thousand thousand worlds (ten trillion earth), and it was Buddha (saisho ojin) that appeared on this French land about 2,600 years ago, with this 3,000 large thousand worlds as one French land. Currently, there is no Buddha (Nyorai), who is an honored Buddha (nyorai) in this land of France, but it is said that after 5.67 billion years, Miroku Bosatsu will become a nyorai and appear as a response.
Also, in addition to this French land, there is France, which also has 3,000 large worlds (100 trillion earth), and on the west side of our French land, there is Amida Nyorai's Western Paradise World, and on the east side, there is the Eastern Joruri World or Myoki World, and there are Yakushi Nyorai and Aki Nyorai, respectively, and Dainichi Nyorai is in the French land called the Myogon Pure Land.
Each Buddha combines the three bodies of Dharma (Shinnyo/Buddhism truth itself), revenge (the Buddha's work), and response (appearance appearing before sentient beings and being indoctrinated), and they are struggling in each French land to save sentient beings.
People who have attained enlightenment and have three bodies are called Buddha and Nyorai. Therefore, all the Buddhas named Nyorai are equally great people.
So, when it comes to whether each Buddha is the same or different, of course, it is a different Buddha statue.
Therefore, with regard to the Dharma as Shinnyō and Mari, even if they are the same as Nyorai, revenge and response for indoctrination are different depending on causality (cause or condition) such as vows and ascetic content for attaining enlightenment.
However, they are all intellectuals who know everything about each other, and both Buddha and Amida Nyorai can take care of each other as if they were their own. Therefore, even in Buddhist scriptures, it is naturally possible for them to mention each other.
Excuse me for making it this far due to the character limit. Just for your reference.
