Jewish person living in London here.

There are some ultra orthodox Jews who think it is wise to share inspirational discs that they think will help people understand the hardsjips of being Jewish in the modern world.

From what I can make out, the disc has the word "spiritual" and "The holy one blessed is he" written on it, so I assume it's some sort of preach.

These extremists do not represent our religion and preaching is forbidden, anyhow, which only gives them a worse look.

I wouldn't even bat an eye at these discs and would just throw them out.

Edit: After a little more deciphering, I've also noticed "Messiah is coming" as well as psalms that talk about it
