What is the meaning of memorial services for ancestors?

I read it.
I think your idea makes sense.
Buddhism is a relationship between oneself and the Buddha, and it's a path of leaving reincarnation and becoming a Buddha yourself, and it's important to believe in the Buddha yourself.
Therefore, I also wonder if they will stick only to memorial services for ancestors. I think your faith is correct.
Each person has a different relationship with their parents and relatives, and they are born, raised, and have different ways of living. It's natural that relationships differ from person to person, and I think it's okay for each person to have their own way of thinking and making memorial services for ancestors.
Not only blood relationships are important; since we live in various relationships, we sometimes sincerely put our hands together with those who have been so indebted to them and pray that they will be at peace.
Since Japanese Buddhism was introduced from China and Korea, it probably includes elements of Confucianism. Ancestors' memorial services are one reason for that, aren't they? Therefore, it might be better to say that ancestral memorial services are included as a style of Japanese Buddhism, or that ancestral memorial services are included in Japanese beliefs.
So I think they each have their own way of thinking and making memorial services for their ancestors.
I think it would be good if you also think about memorial services for your ancestors in the context of your own way of life up until now.
We are all connected as a way of thinking. Even if you usually live your life thinking that it's just other people, it actually means that the person next to you isn't a complete stranger. In other words, if you go all the way back, everyone is connected. Actually, everyone is connected regardless of country or world. Imagine going back tens or hundreds of generations, or do some math. The answer is clear. We are all relatives and all ancestors. If you think about it, the way you look at it might change a bit, doesn't it?
But faith is your own, your own. It's the relationship between you and the Buddha. If you believe in the Buddha, it's yours.
Please continue to work hard by deepening your own faith.
I sincerely pray to the Buddha that your future religious life will be even richer. Shishin Gassho Nanmu Amida Buddha

I liked that. There are people whose parents have died, but there are probably no children born without parents.
You seem to be wondering what can be done about the fate of the dead.
Fujimoto Akira “Why can merit be converted?” If reading by buying or borrowing (Kokusho Publishing Association) is bothersome,
The booklet “What is a memorial service?” on the Seikyo-ji Temple website It is made so that you can read it for free. Please take a look.
Simply put, in Hinduism and Confucianism, memorial services for the deceased somehow go away, but it seems that no religion even knew whether they were effective. It is detailed in early Buddhist sutras that Shakyamuni taught logic and the presence or absence of effects. It is not an invention of Mahayana Buddhism. I previously wrote in my doctoral dissertation.

If you don't mind, I hope you can refer to the following humble remarks.

“On the significance of funerals and memorial services”
http://blog.goo.ne.jp/hidetoshi-k/e/d2c3793b56451efdff407f7090851dc1

In addition to being an opportunity to receive a thankful and precious Buddhist relationship, it is also a good opportunity to accumulate “self-interest and altruism” in order to move towards enlightenment and nirvana.

“... I want both myself and others to think clearly about how to strengthen Buddhist relationships and work hard on ascetic practices and merits in order to ride the good flow towards enlightenment and nirvana, and strive to understand their significance as much as possible, even in various memorial services. ・・”

Also, for the memorial service, please refer to the following humble law story.

It's called the most important topic, and since it's the most familiar portal for many people, there's a lot of information. When demand is high, so is supply. Family-friendly books and websites say things suitable for the home, and if you go to a university, there are many Buddhist history and ideas, and if you go to an ascetic dojo, there are many ways to live in zazen or Buddhist ascetic practices. That's all.

As for why it's important, it's a good idea to delve into “what is Buddha in the first place.”
Buddha is a state of peace away from suffering. Well then, when it comes to how suffering occurs, it's going to be long, so I skip the midway formula, but in Buddhism, I think “various kinds of suffering occur depending on the way of thinking that I am the person I am the reference point.”

Well then, when it comes to how to stop your own standards, this is where various training methods for each denomination come up. [One of them is an ancestral memorial service].

First, close relatives, then ancestors whose faces you don't know. Furthermore, if it's Sega Gaki, it's all Gakibutsu, and if it's a memorial service, all the victims. If it's a livestock memorial service, all the livestock. If it's a needle memorial service, everyone loves needles. If it were normal, it would be absolutely everyone. Yes, it's [everyone everyone]. The way we all live is the medicine for my standard way of thinking, isn't it?

Everyone is everyone's ultimate... everyone in the universe in the past, present, and future is called Buddha.
So once we break free from reincarnation as individuals, we are Buddha, we are originally Buddha even during our lifetime, and we are living under the Buddha's guidance. ←Let's replace Buddha with the world.

Here, the first connection that is most familiar and easy for many people is their parents and ancestors. (Incidentally, people in India or elsewhere also hold memorial services like “First, parents in this world, then parents from previous lives...” (The origin of Confucianism is an old trend.)

So if memorial services for ancestors are hard to come by, then a Buddhist memorial service is fine. The principal image will be enshrined on the Buddhist altar. That's so great.

However, it is also common for ancestors to become close to them by continuing memorial services for ancestors. There are quite a few people who, even if they are parents and siblings, have come to feel close to them since they passed away.
