A Chabad-Lubavitch shaliach suffering from Amyotrophic lateral sclerosis (ALS) has captured the heart of viewers, in a video musical that went viral. Posted earlier Friday, it has already racked up 120,000 views on Facebook alone.

The video features a song, “Shine A Little Light,” written by the ill shaliach, Yitzi Hurwitz, director and spiritual leader of the Chabad Jewish Center in Temecula, California. The father of 7 has been suffering from ALS, a rapidly progressive, invariably fatal neurological disease also known as Lou Gehrig’s disease, since 2013.

In that time, he has become almost totally paralyzed and has lost his ability to speak. However, he is still able to smile and communicate by moving his eyes and directing his gaze at letters on a computer screen.

Friends and supporters of Hurwitz came together to make the music video and brought musicians from all around the world to perform in the video. The film intersperses footage of Hurwitz from before and after he took ill with performances by various American, Israeli and British Jewish singers.

Hurwitz’s own singing voice is heard at the beginning and end of the video, from 2008 when he was still able to vocalize.

“Shine A Little Light” is a hopeful song about people — individually and together — working to bring a brighter future.

“I love when I get visitors, because when I am alone, I start thinking about myself, and like everyone else, I have things that bother me, that is totally out of my control. When I get visitors, my focus is all about them. It is my hope that Moshiach will come soon, and all suffering and pain will end,” he wrote in his latest post.
