About continuing with the temple and Yukoto

I read it. You're in a very difficult situation, aren't you? I'm sorry for your feelings.
I think it would be nice to say something to the temple... but after all, it is necessary for everyone to talk about it a little more carefully.
The temple is a corporation. It's not a house thing. It's not personal.
There is a chief priest who is a leader who spreads the faith as a representative. There is a temple family that supports it at the same time, and there are devotees as believers.
We are cooperating together to enliven and maintain the temple. That is the main premise, so your current situation and your parents' thoughts will be reversed.
It's a harsh way of saying it, but it's not something that should be decided within the family just about the immediate future.
Until now, there are parts that have been good about that, but we are now in an age where that doesn't work anymore.

Those who follow the teachings of Buddhism and have firm faith and are unable to properly communicate them to everyone are not eligible to become chief priests.

Please don't be alarmed, but once again, you and everyone, should think carefully.
It's an important teaching, and each one is an important part of life.
Above all else, it's a temple that has continued to exist based on its long history, so please consider it with a sincere attitude!

Your life is yet to come. Please don't give up and don't get swept away!

Temples are not hereditary, so you or your family don't necessarily have to inherit them. If someone else is suitable, I think it's okay to hand it over.
At that time, I think it's okay to get a proper retirement allowance and leave the temple, and if possible, live together as is.
The important thing is to properly convey Buddhism and support life while managing temples and graves for parishioners, believers, and others.

However, for me personally, if there are many parishioners and it seems that the temple can continue steadily in the future, and furthermore, if you are not currently working hard towards any dreams or goals, then I think you should become the chief priest.

The fact that the chief priest must be a man is itself out of Buddhism, so I think that area must also be corrected in the future.
There were also many women among the Buddha's disciples. There is a record that they had discussions on equal terms with male disciples.

Also, answering questions like Hasunoha, for example, is one of the monk's roles, isn't it? Please read through the various questions and answers here. What do you think? A monk's job is not just to perform rituals and manage temples and graves. Rather, they are auxiliary roles, and it is important to work for parishioners, believers, and the general public. If you have even the slightest desire to support the lives of parishioners and believers, I think you have what it takes to become a monk.

By the way, a nun I know sings songs called Japanese hymns and sermons to proselytize.
If you have any special skills, you may be able to make use of them to proselytize in a way that your father cannot do.
Why don't you relearn about Buddhism and the role of a monk again? On top of that, if you don't want to be a monk, I hope you tell your parents about it and move on with your own life.
The Buddha's teaching was that you should live according to your own ideas based on the truth. (Self-lighting and Dharma lighting)
If you live according to someone else's will, that is contrary to the Buddha's teachings.

“My older sister's husband (person who came from a normal house: not adopted yet and in the trial period) works at the temple, but recently the current chief priest (father) and mother have decided that “he will not be adopted by my son-in-law in the future”
I mean, are my older sister and her wife convinced of this decision? Isn't it going to change anymore? So, suddenly you're in trouble. After all, my parents changed my mind, and I thought it would be nice if I became my son-in-law.

That's a troubling problem.

As was answered earlier, I think it would be better to first discuss what will happen to the older sister and her wife. Is this a “trial period?” So maybe it's not that much of a problem.

On top of that, if Myon-san herself isn't that picky, go for “Choice 2.”
“Matchmaking now?” I think that's a common feeling, but it's still a common story in our sect (Jodo Shinshu Honganji school).
There is also a situation where the number of temples with succession difficulties is increasing, and in the Honganji school, there is also a successor introduction system operated by Motoyama.

It's an age where Buddhism and temples have been re-examined, so you may be able to meet people who have a passion for temples. Even through matchmaking, you can meet great people when you meet them!

I personally don't recommend option 3.
Since it is a temple that has been protected by inheriting the thoughts of many people since ancient times, there is no easy choice to stop. In a sense, it also means that my parents' house will disappear.
(Very depopulated areas may be unavoidable)

My temple too
Until I joined, many succession candidates entered and then continued to leave.
So it seems that the parishioners were quite worried.

Did your older sister and her husband accept their parents' ideas?
If your older sister is a monk, take over as the chief priest,
That husband can also be a monk.

Is the possibility of an older sister marrying at all zero?

I think Buddhism teaches us how to live.

Whether it's a nenbutsu or a title, they teach us how to live by believing in it and supporting each other and helping each other as a pillar of our own way of life.

There are believers around the temple who are based on a sense of faith cultivated over many years, and recently, that feeling has become weak, and the current situation is that they have left the temple.

Now, as for your own progress and decline in the future, regardless of whether you are aware of it or not, you were born in a temple, started giving offerings from all the believers, and were able to live your life supported by the feelings of many people.

It is thanks to all the believers that I was able to do what I wanted to do, and that I was able to follow the path I wanted to follow.

I'm sorry for saying it so harshly, but have any believers ever thought about why they decided to become a parishioner at your temple?

The life of your family is also included in the accumulation of a sense of faith that you thought you would become a parishioner precisely because the chief priest at that time was someone you could trust when arranging a funeral.

Based on that, it's not about being sacrificed by everyone, becoming a successor to the temple, etc.

I would like them to firmly face the fact that continued in the accumulation of their faith.

If you come into contact with the Buddha's teachings within yourself, feel joy, and want to convey them, then become a priest (wouldn't it be a good idea to think about what this phrase also means?) You can do it, and if it's impossible, you'll have to search for another method,

As the title suggests,

I feel that the time has come to take a serious look at my own way of life and make up my mind.

In any case, I pray that you will be able to come to a conclusion without regrets and in which you can feel joy.
