What is
Yesodei Hadas?
Imagine a child sitting on a treasure chest containing a king’s ransom in diamonds. The child has his hand out, begging passersby for a few dollars so he can buy himself some food. What should we do? Should we give him the handout he is asking for? Or should we say to him, “Hey, take a look at what you’re sitting on!”
Yesodei Hadas opens students’ eyes to the beauty and glory of Yiddishkeit.
We provide intellectually satisfying answers to commonly asked questions.
We instill in them pride and confidence.
