Phillys,
Moshe Rabbeinu spent a few seconds Davening for Miriam. All he said was, Kel Na Refa Na La.
Anyhow, there’s a big difference between trying to understand the logic behind something and making one up. Not every Segula is magic. Often there is a distinction between a Segula and something which is Mesugal. Wearing a fox tooth to be able to fall asleep is a Segula, something not explained by medical or Avodas Hashem. Washing Netilas Yadayim with a full Kos is Mesugal for Parnassa. Both examples, by the way, are from the Gemara in Shabbos. Going to the Kosel for forty consecutive days is not meant to be a magic trick. It is meant to be a form of devotion to your Tefila, just as you can understand how fasting for three days gets your prayers heard faster.
