Diaspora refers to anywhere outside of the land of Israel.
Diaspora Jews are Jews living anywhere but in Israel.
For too many years, I lived in New York while dreaming about living in Israel.
In fact, whenever I was asked where I live, I would say, I work in New York but my heart is in Israel.
A few years ago, I fulfilled my dream and I now live in Israel. I recently had heart surgery and now even my heart is here full time and I am no longer a Diaspora Jew.
To all my loved ones and friends, and to everyone I know, when the time is right for you, leave the Diaspora and come join me.
