About the hand memorial service for opening eyes

Thank you for your question.
It is said that they will do a memorial service at home, but even if you don't split the bone, you can do a memorial service at home if you have a Buddhist altar (small but a reasonable size) and a deceased person's place plate (past book in the case of the Jodo Shinshu sect). Of course, if you want to feel close to the remains or if you don't make a grave, I think it's good to split bones.
An open eye is used as a Buddha statue or seat sign, so it is not used as a remains.
The reason souls don't dwell in the remains is because souls have gone to the Pure Land.
Opening eyes is a ceremony for the bereaved family rather than for the deceased. Whether they try to open their eyes, the deceased will always attain Buddhahood. By opening their eyes, bereaved families will be able to see the Buddha statue as a Buddha and the seat plate as a deceased person with their own eyes.
It's best to put your hands together every day. However, there's no need to force yourself when you're away from home.
Incense sticks can be used every day or from time to time, but they can also be around the anniversary of death, Higan, Obon, and memorial services. To the extent that I don't want to smoke. Also, incense sticks can cause fires, so please never leave the fire on when you go to bed or when you are away. If you continue to use incense sticks, please change the position where you pierce the incense sticks slightly every time. That's because if incense sticks that have caught fire remain in the ashes, the new incense sticks will fall over and cause a fire.
Also, there are various types depending on denomination and regional nature, so be sure to ask the monks of your denomination as well.

Thank you so much for your response.
They seem worried about becoming an unrelated Buddha, but don't worry about that.
That's because you, your father, and your family are all going to the Pure Land. It's like we're all moving to the Pure Land. You don't have to worry about anything. Therefore, please do the memorial service to the extent that you can do in a form that is safe for you.

I read it.

You should keep your bones at home, but I don't recommend leaving them at home. Jibou recommends that bones be buried in a tomb or temple as soon as possible once they have finished shedding as soon as possible.

In the Jodo Shinshu sect, it is taught that when people die, they are allowed to go to the world of the Buddha called the Pure Land. Even so, if the bereaved families left behind say they are lonely and lonely without letting go of the remains of the deceased, people who wanted to go to the Pure Land will also not be able to go.

I think what we can do for those who have passed away is to say, “We are living a happy life, so please feel safe and go to the world of the Buddha.”

Bones are stored in graves, temples, etc., and I think the most refreshing thing for us is to think back about people who died through Buddhist altars or graves.

Nice to meet you, Mari. I read your question.

You care about the deceased so much that you want to make a memorial service, don't you think?

An eye opening memorial service is sometimes paraphrased as “putting in the soul,” so where is the soul? You'll get lost.

Think of an eye opening memorial service as a sign to begin a memorial service. It's about making a declaration that you will put it on hand and begin the memorial service.

A memorial service is “not forgetting the deceased,” so please keep your heart on it and cherish it forever. I don't think it's necessary to stick to the shape.

I'm praying that one day I can let go and watch over the deceased without being too particular about memorial services.
