“There is such a thing as emet (truth), and there is such a thing a thing as emuna [believing].  Real joy is a combination of truth and believing.

If emet and emuna are both working strongly inside of you, if you believe what you know, and you know what you believe, then you are filled with joy.

If your joy comes from emet and emuna, from truth and believing, then it’s called Jewish joy, holy joy.  Otherwise it is just called pagan joy.” ~ R’ Shlomo Carlebach zt”l
