Any Buddhist altar is fine, but if there is no religious spirit or Buddhist spirit, it will simply be a large box to enshrine the principal image, enshrining a plaque called a Buddhist altar.
No matter what the people around you are, it is important that you develop a Buddhist spirit, merit, and sense of the law yourself through your relationships with your grandmother and deceased.
To that end, it is necessary to apply for Bodhicitta.
What is important at the funeral and on the first 7 days is the Bodhi Heart.
The fact that the Buddha also passed away and the memorial tower, the stupa (stupa), was built probably not just to make a memorial service for the deceased Buddha.
Rather, it is proper that the form of building a memorial tower, holding a Buddhist altar, making a table, and building a tombstone for the first time after making a vow, inheriting the spirit, improving one's humanity, recompense, and building a tombstone, which is the root of memorial services, is the spirit of a royal memorial service.
In Buddhism, the spirit of Bodhicitta is explained in the Sihiro Pledge.
I will save people in need in the first generation and guide sentient beings in my own delusional self
2. Cut off your worries and guide bad hearts that torment yourself and others
Learn the 3 Dharma and develop yourself. Use everything as learning to guide your self well
4. I will fulfill the Buddha's path, reveal my true nature, and guide everything well
Even though there are memorial services for ancestors in Buddhism these days, I feel that the spirit of improving one's own humanity is lacking. You don't have to be a Buddhist to do memorial services for ancestors and memorial services for those who have died. However, Buddhists don't just hold memorial services for the dead. Furthermore, they have a wonderful spirit that saves even those with whom they are related and leads to supreme humanity. The symbols are temples, graves, Buddhist altars, pagodas, and memorial services. All of them are also a great spirit of salvation to save oneself and save others.
What is Bodhi Heart?
There are also people who explain that Bodhi Heart is a spirit that makes people superior to oneself.
Since I myself have lived to this day due to the blessings and benefits of so many people, the Buddhist spirit of salvation called bodhicitte, and the spirit of making my family and others smile with the spirit of mercy and wisdom are the spirit of Buddhism, and it is a living Buddhist altar.
Buddhist altars are a symbol of my heart. Of course, the principal image is also found on Buddhist altars, but it is in the body and mind of the inner self that the body and mind of the Bodhisattva mind lies. Please buy it with that feeling. That is the Buddhist religious spirit.
