The article is about a famous Rabbi named Yitzhak Kaduri who apparently was able to contact demons. Pretty strange thing for someone who's a devout man of God to do.

Kaduri was the only person capable of writing amulets that have the power to bring success, heal, improve fertility or change reality for the better in some other way.

In Kabbalistic thought it is believed that amulets tap the powers of demons and spirits and use them to perform miracles. In order to harness these supernatural powers, it is normally necessary to force these demons or spirits to take an oath. This is considered incredibly dangerous since the demons and spirits, once released from the oath, seek retribution.

Asked once if he forces an oath on demons when he writes his amulets, Kaduri replied, "God forbid! It is forbidden to force them to take an oath. I only ask nicely. If they want to listen to me, they listen. Most of the time they respect me because I am so old."

Hmmm.
