Hello, Decadence from Regimental.
As you said, “It's not good to judge by appearance or gestures.”
Even though we know that very well, we often make judgments based on our looks and gestures.
I think the three requirements you raised are certainly characteristics of “untrustworthy people/unreliable people.”
However, “you can trust or cannot be trusted” or “can't be trusted” is not due to the person's humanity or personality, but your “convenience” is probably the standard for judgment.
In Buddhism, it means “suffering.”
I was told that the original meaning was “something that is not convenient for me.”
Seen from other people's point of view, even if it's someone you can trust enough, based on your own “convenience,”
Have you ever made a judgment that you are “unreliable or untrustworthy”?
When we dismiss other people as “that kind of person,” alas, before we know it, we use “fit or not fit” as a standard for “our own convenience.”
Surely, when deciding whether you can trust another person or not, you are making a decision based on “your own circumstances.”
Leaving “one's own convenience” means moving away from “suffering.”
It's very difficult, but when you cut off “others,” just a little bit is enough, so I would like you to look at the current state of your “self.”
