I want to know the meaning of Hatsubon in an easy-to-understand manner

I read it.
Obon is based on the saying that important people and ancestors who died earlier come from the Pure Land of Paradise and spend time with us alive.
Naturally, those who have passed away have already successfully attained Buddhism together with many of you in the Pure Land of Paradise. And they continue to gently watch over us as we live at any time. Then we go back for Obon and spend time together.
So we picked them up at the grave early in the morning of the 13th of Welcome Bon and before it got hot, and we went back to our home together. Before that, I'll make bonsai decorations for the first Bon Festival. I think there are regional differences in bonsai, so I think it would be a good idea to ask the family temple how to decorate them and what to offer. There are also Obon pamphlets for each denomination, so I think you can refer to them.
In any case, it will be the 13th and you will have a relaxing time. I also think relatives and close people will be at home for the Obon memorial service on the 14th and 15th. Therefore, they are given incense sticks and talk slowly, and depending on the region, they enjoy alcohol together and spend a peaceful time with their ancestors.
Also, people who come here will offer incense, so I think it's generally okay to prepare return gifts that are just what you feel like. I think it would be good to have a slightly larger number of return gifts that you can return if you have left over. In any case, don't overdo it because of your feelings.
Also, I think the monk from the family temple is here to pray for the Tanaka Sutra. Please ask Bodaiji about that beforehand. The offerings of the Tanagyo Sutra also vary depending on the region and the family temple, so I think it would be better to ask the family temple for guidelines beforehand.
And as for Okuribon, I'll send it to you after the evening of the 16th gets cooler. At that time, we will also offer beef and horse rides made from eggplants and cucumbers by laying out makomo and sending them to you. After all, this offering also differs depending on the region. There are cases where they are sent by the road outside the entrance, and there are also cases where offerings are made to the nearby riverbank, and at our temple, everyone makes offerings on the south side of the main hall of the temple.
In any case, it is said that it is good to “welcome your loved ones early on the 13th, spend a leisurely time together on the 14th and 15th, and send them off slowly on the 16th.” Please welcome them with all your heart.

　Obon is a folk event. Although it is a Buddhist event, it is also a folk event where Japanese people honor their ancestral spirits and interact with their ancestral spirits.

What is called Obon is explained in the Buddhist theory of the Obon Sutra.
“About the season and purpose of Obon”

(This is an answer I gave 15 years ago.)

So, when it comes to whether Japanese Obon events are held in line with this Buddhist theory, the Obon Sutra, this is not the case. As I mentioned at the beginning, it is carried out in a form that is in line with Japanese ancestral beliefs. Welcome fires, bondana (spirit shelves), and okuribi cannot be explained from Buddhist teachings. Even when it comes to ancestral worship, which respects the spirits of ancestors, it varies depending on the region and lifestyle culture. Mountains, underground, and offshore islands can be considered as places where the dead go. There's no saying which one is right and which one is wrong. That person, the “place where your ancestors are,” which others have become accustomed to, is the correct answer for that person. The belief that the spirits of those who died first hid in the mountain behind their homes, were purified by repeated memorial services every year, and climbed a high mountain called a sacred mountain called a local sacred mountain is widely seen all over the country.

It's not like our ancestors who climbed a mountain just went and didn't come back. They light a fire to welcome Obon, welcome them from “the other world” to the bonsai, and entertain them with offerings and meals. Before that, families gather and talk with their ancestors. When the Obon festival is over, I'll put on a fire to see you off.

I get asked this question from time to time about Obon. “During Obon, we welcome our ancestors to the Spirit Shelf, and we also pray at graves. Where are your ancestors?” and. The Buddhist answer is, “None of them died. This is because he received the commandment, became a disciple of the Buddha, and left for the Buddha's world. The tomb is a sanctuary for precious remains, and it is an important place as an entrance to the Buddha's world.” So that's it. The answer from a folk standpoint is, “The spirits of our ancestors watch over us everywhere we go. So, originally, they always fly to the side. They can stay. However, it is necessary not to rely on ancestors forever, but also to be independent. That's why they're always there, but they've been handed down that they only stay during the Obon season so they don't rely too much on their ancestors.” and.

There is a character limit, so this is the end of the explanation. Also, please ask your questions.

Hello.

Your husband passed away, and it's hard to change your mind. I think it's a matter of course. It's fine.

I'm sure your husband sees you from a distance on a daily basis. And I'm sure they'll come back to places close to Obon and eat meals together. Be sure to get ready to pick them up, pick up an offering that the deceased loved, and enjoy it as if you were eating it with the deceased on Obon Day. If getting ready is difficult, let's do it together with relatives and neighbors.

Don't worry, there's no such thing as the deceased being unable to attain Buddhism because you don't give incense sticks or sing Namu Amida Buddha. Feeling something smell may be mental. If it continues, you may consult your doctor once.

I'll send it to you on the 15th, but don't worry, I'm also watching you softly from a little distance (this doesn't mean you haven't attained Buddhism).
