The Art of Happiness

And we've learned from it that the book that Hirsch left on his nightstand, he did not need to take it with him because he was going just to dance one night through and he'd be back early the next morning.

The book that Hirsch left on his nightstand was The Art of Happiness by the Dalai Lama.

And in the book, Rachel Goldberg Poland also writes of that first day, quote, I remember a girl Hirsch's age calling her father from one of the hospitals saying they would not let her in to search for Hirsch.

I remember her father saying, Roni, you are not to leave until you get in and find if he is there.
