His name is Yahuah, not Voldemort. Stop treating it like poison and start using it with reverence and respect.
It's not my place to speak for the author . . . but this is FR so I will anyways. I see a lot of reverence and respect in treating G-D's name as too holy to speak or to write out fully. It's also a very old tradition, one that has been part of an amazingly successful path to following G-D.
It's almost miraculous how well the Jews have survived for 3000+ years of following the Law, compared to the false religions that surrounded them in the days of the prophets - none of which have survived. It's almost like G-D knew what he was doing and got it right when He told the Jews how to follow Him. Who are we to argue with that much success . . . or with G-D?
Pollster1 answered much better than I could. However, I’ll point out that the root of this Torah tradition is in the 10 Commandments, not to use His Name in vain. We only write this Name in holy text, do not say it and don’t write this Name wherever there’s a chance of erasure.
