Deuteronomy 18:10 "There shall not be found among you... a soothsayer or an enchanter"
Superstitions are signs or omens of things supposed to happen, that some people claim to believe in.
An example of a superstition is if we hear someone say, "The first thing I saw today was a black cat so I know that I will fail my test!"
We are not allowed to decide what we should do depending on a superstition. Only the Torah can guide and help us to determine our actions.


Confused about this I'm confused about this and other references to mediums and such. How is this different from the visions had by prophets of old? And isn't Kabbalah a practice that can be utilised to reveal that which is hidden, including future events.
And what if a person can sense future events before they happen without engaging in any ritual or using "tools". Are they breaking a commandment?
