To regret past mistakes: I see this as a wrong way to reflect.

Reflection is generally considered a virtue, but
Reflection when accompanied by feelings of regret
I don't see it as a good thing.
Because,
Feelings of regret are seen as unrighteousness.
Because it is considered a bad thing.
The evil effects are so bad that they fall into beasts, asuras, and hungry shinigami ghosts.
Yes, that is considered a spooky thing.
Now then, I will talk about a good man who has no regrets.
What is the correct method of reflection?
To do so you must use #Aminlogic my way off Four full-time shifts.
#1 Work to "remove the evil that has already occurred"
#2 Work to "not create new evil"
#3 Work to “bring forth new goodness”
#4 Work to “increase the good that has already occurred”

Through deep awareness of these four steps through meditation,
specifically to eradicate the
New evil or the new badness,
birthing the new good, the goodness that has arisen.
The results obtained through four regular shifts is beneficial.
I’ve must practice and maintain a strong determination.
Furthermore,
By living your best life now
We are building the foundation for a better future.
.
Don't chase the past
Don't wait for the future.
Just love in the present moment,
You have to be strong and live strong.
