Yankel, a survivor of the Holocaust, runs a bakery in the New York neighborhood of Crown Heights. One day, he explained: "Do you know why I'm still alive today? When I was a child, only a teenager, I was with other Jews on the train on our way to Auschwitz. Night was falling and it was freezing in the wagons, a real deadly cold!

The Germans left the trains on the side of the road all night, sometimes for several days in a row, without any food and any blankets to keep us warm. An elderly man was sitting next to me, a sweet old Jew from my city. I knew him, but I had never seen him like that. He was shaking from head to toe and looked terrified.

I then wrapped him in my arms and began rubbing him to warm him up. I rubbed his arms, legs, face and neck. I begged him to stay strong and hold on. All night long, I was keeping this man warm that way. I was tired, my fingers were frozen, but I did not stop rubbing the body of this man.

Hours passed like this. Morning arrived again and the sun started to shine. A little ray entered the cabin and I looked around the wagon to see if any of the other Jews had survived...

To my dismay, all I could find was frozen bodies, and all I could hear was the silence of death. No one else in the cabin had survived the night, they had all died of the cold... Only two people had survived: the old man and me. He did because someone had kept him warm and I did because I was keeping someone warm.

Let me tell you a secret of Judaism: when you warm the hearts of others, you warm yourself, and when you seek to support, encourage and inspire others, you find support, encouragement and inspiration in your own life."
