As a volunteer at the Nurturing Place in Jersey City, Jack Egan takes great joy and inspiration from his preschool charges.

“That place is delightful,’’ he says of the York Street Project’s early-learning center for the children of homeless and low-income women. “I love it.”

Having helped out in the classroom for more than 17 years, Egan has found life lessons in the preschoolers’ “inborn wisdom’’ that he shares in his new book, “The Colors Love Each Other: The Nurturing Place Stories and Reflections.”

Proceeds of its sales will be donated to the York Street Project.

“The little children here teach us probably as much or more than we teach them,’’ he writes. “And, perhaps, the greatest thing they teach us, or re-teach us, is what we have forgotten. They light up our eyes and souls again so that we see, through their eyes and intuition, the wonder and delight in the lady bugs and night crawlers, in the butterflies and birds, in all the countless and colorful life forms traveling with us on this green and blue earth of ours.’’
