Re: Nazar Lagana
If read different disciplines / train of thoughts (aka religions, healing practices, martial arts) ... you will notice a lot of them work with energy.
There are scientific proofs that they do accomplish impossible or demonstrated intresting influences on others (let me know if u want me to look up exact cases for you).
Its kinda like mind over matter philosphy (after all if you break down material, EVERYTHING is just pure energy - matter is trapped energy).
Coming back to your question. I beleive praying / evil eye also involves manipulating these energies (intentionally or unintentionally). The stronger your belief / emotion, more control you can exert.
My Team Leader (at work) is a "Riki" Master (another discipline which controls energies for healing purposes). She once told me, she is just getting to a point where she can see auros (energy sphere) around people. This tells her the mood and if they people are generally good / bad.
She has also went through some experiences in her life - and she survived through them ONLY because she practiced Riki. I kinda beleive her.
