In most cases, decent people pick up valuables found on the street for only one purpose: to find the rightful owner.
It is known that it is forbidden to appropriate other people's things, but not everyone follows this rule.
Even if it seems to you that the found object is a signal that luck is on your side again, this is a misconception. Experts note that the found object is still someone else's. It will not have the most positive energy.
Esoteric experts believe that such a situation is a kind of test for a person. If he passes it with dignity, returns the thing to its owner or passes by, then this will have a good effect on him in the future.
If you give in to temptation, the outcome will be unfavorable.
Even if you are a rational person who believes in the scientific picture of the world, not everyone shares this worldview.
Some people use valuables in magical rituals.
Therefore, picking them up would not be the best idea.
