You're looking back on the memorial service you perform with a very humble feeling. I'm sure both the Buddha and his late father are happy with Komachi's humble feelings.
If you search on the internet, I think various explanations will come up. It's not a perfect explanation based on the limited number of characters and the extent of my knowledge, but I'll explain it for reference only.
Basically, I think it's about devoting one's heart to the Buddhas, Bodhisattvas, and ancestors.
Various memorial services have been explained as specific actions to that end. As an example, there are three types of memorial services.
1. Ri memorial service - offering flowers, incense, lights, food and drink to Buddhas, Bodhisattvas, and ancestors
2. Memorial service - read sutras and recite mantras for the Buddhas, Bodhisattvas, and ancestors
3. Memorial service - practice Buddhism and practice the teachings of the Buddha
The act of offering the first incense or offering is a majesty for the Buddha, Bodhisattva, and our ancestors, and I think our hearts when we offered it at the same time will also be majestic.
Also, when reciting sutras 2, it is said that the person who recited the sutras will receive merit from chanting the sutras. That's why we recite something called “conversion” after chanting sutras so that the merits of chanting sutras can be transferred to the Buddha and ancestors. They chant the merits of chanting sutras in order to “turn (turn) it around” to their ancestors. If you make a memorial service, the person who performed that act will also receive merit. The purpose of receiving a reward is not good, but I think “being able to sort out my feelings” can be taken as a reward for doing a memorial service.
① Who are memorial services for?
- As already mentioned, we do it for the Buddhas, Bodhisattvas, and ancestors.
② Why is a memorial service necessary?
-I think this is because it is a courtesy to show respect to the Buddhas, Bodhisattvas, and ancestors, and is performed to honor the virtues of Buddhas, Bosatsu, and ancestors and receive virtue.
③ What is the proper way to hold a memorial service?
-In the Soto sect, the term “majestic Buddhism” is often used. Living according to proper discipline and manners is a prerequisite for learning Buddhism, but it is used to mean that the premise is Buddhism itself. Please work at Komachi's family temple with all your heart in accordance with its purpose, such as daily work at the Buddhist altar and the memorial service for the anniversary at the family temple.
