years ago I visited Majdanek, one of the most intact concentration camps. The tour ends in a huge heap of ashes. There I was, standing in front of those ashes, thinking about the meaning of life, after seeing all those gas chambers and crematoriums. I was feeling very sad. Then a small group of young haredim arrived at the other side of the heap. After a while, they started singing a very beautiful song. I didn't knew the song, nor could i understand one word of what they were singing. You see, i'm not a very emotional person, but when those guys started singing that song in front of those ashes I started crying like a baby.
Until today when i remember that moment it gives me chills. It's one of my top 5 memories for sure. It would mean a lot to me to know what song they were singing, and if possible, the translated lyrics.
Here's all I was able to record while crying [audio only]: https://youtu.be/QDH-wQ02OR0
