An ultra-Orthodox Jewish couple, a Muslim mother, and Taoist met on a subway train during a Christian festival. The result was a message of harmony seized on by tens of thousands of people.

It’s not a joke, but rather the story of a chance encounter that produced a photo of the Hasidic Jewish couple sitting next to the Muslim woman as she nurses her baby on the New York City subway. The photo, with the short background tale of how it came to be, has gone viral after it was published on the Facebook social media website.

The post has received some 53,000 likes and nearly 41,000 shares since it was posted on Sunday by Jackie Summers, a self-described Taoist.

“A Taoist (me) gives up his seat so a Hasidic couple could sit together,” Summers wrote using a term that describes certain sects of ultra-Orthodox Jews. “They scoot over so a Muslim mother could sit and nurse her baby, on Easter Sunday.”

“This is my America: people letting people be people.”

The photo was taken on the F Train, which runs between Queens and Brooklyn.
