Hi Rabbi! I hope you are doing well. Some sephardic family members of mine have recently approached me and urged me to use "blue beads" on our baby's crib (due in three weeks, G-d willing) to protect it from the "evil eye." I responded that, as an observant Jew, I believe there is no other power other than G-d, thus, I need only turn to Him for protection. They were quite upset by this and insisted I reconsider. What exactly is the rationalist approach to amulets such as blue beads and chamsas in Judaism? Are there any sources on the subject so that I can show that our sages rejected such seemingly irrational and pagan practices (which seem to be rampant in many sephardic circles)? Thanks!!
