I can’t truly answer your question but what I could do is explain what a segualh is REALLY supposed to do.
For example (then you”ll chap easier), there is a segulah to have kavanah during bracha of “Al Netials Yadayim” to become rich. At face value, you say “oh wow so easy so lets strike it rich!” But then you dont see good results. Why? I did the segulah?
Well, I heard the real reason how it works & this is much harder:
If one will have kavanah in that bracha, he should focus on why he his washing. Because he is going to eat bread which is the food of man. Now, who sustains us? Hashem! So we’re thanking Hashem for providing us our food. If we would realize that what we have is enough (Someach b’chelko) then we would fill that Hashem gave us mamish what we need!
May we all do/think the emes what Chazal already instructed us becuase the segulahs are only once you chapped what Chazal means.
Have a chag kasher v’sameach!
