My 'Big Life Decision' and the Magic of Numbers

On December 16th, I closed out my ancestral grave and said goodbye to the family temple in my hometown.
After that, on December 20th, I interred my 'parents and ancestors' in a communal grave in the town where I currently live.

The grave in the countryside was located on the temple grounds and, according to the family register, was about 150 years old, but I had rebuilt it 13 years ago when my parents passed away.
That grave has now been closed, and the remains have been relocated to the communal grave.

Closing the grave was something I had planned for a while, as my spouse and I are both over 70 and have moved from the countryside to the town where we now live, making it difficult to maintain the grave, though I did feel a sense of sadness.
Once I actually went through with it, it was a straightforward process; from the moment I made the decision to the completion of the interment in the communal grave, it was a whirlwind of about 20 days involving meetings with the temple and the construction contractors.
During that time, I had to visit the municipal offices in both the countryside and my current town twice each to verify documents, which did not go very smoothly.

I am not particularly superstitious, but the reception number for the communal grave was 49, which felt a bit strange. However, when I looked it up using AI, it said, 'Since 7 x 7 = 49, it is the square of 7. 7 is often considered a "perfect number" or a "lucky number," and because of that influence, 49 is sometimes also considered auspicious.' That put my mind at ease.
Furthermore, December 20th, the day of the interment in the communal grave, was a 'double lucky day' that coincided with both a 'Taian' (a very auspicious day) and an 'Ichiryumanbai-bi' (a day when a single grain of rice multiplies ten thousand times), making it an extremely auspicious Saturday for doing anything. I don't usually pay attention to numbers, but these were days where I felt the magic of unexpected coincidences.

Regarding the closing of the grave, it is not that I had no feelings about it. I had my doubts about whether it was right to end something passed down through generations during my lifetime.
However, I am relieved knowing that by having them memorialized in perpetuity at the communal grave, even if something happens to us, the facility is managed by the government and will continue to exist forever(?).
