An emotional mother whose seven-month-old son died after being reportedly abused by a babysitter’s boyfriend donated his organs – and has now heard the boy’s heartbeat in a young girl.

On one fateful day, baby Lukas Clark was rushed to a hospital for an emergency rescue, but the doctors informed that his condition was beyond any medical help. His shattered mom, Heather Clark, then picked herself up with all her courage, and made the bold decision to donate her 7-month-old baby’s organs that have now saved three lives.

Baby Lukas passed away almost four years ago, but his presence is still felt in Jordan Drake’s life—the little girl who got her heart in a transplant. Last year, in Jan. 2016, his mom met 4-year-old Jordan and her family at Phoenix Children’s Hospital in Phoenix, Arizona, where she heard her dead son’s heart beating in this little energetic girl’s body.

Clark lifted a stethoscope to Jordan’s chest to hear her son’s heartbeat for the first time after his death. At that moment, both mothers cried.

“It was magical, it was crazy, it was sad,” Clark told CBS News. “There’s absolutely no word, no explanation for it besides just magic and wonderful.”

At birth, little Jordan was diagnosed with a congenital heart disease. The doctors at Phoenix Children’s Hospital told her mother, Esther Gonzalez, that Jordan needed an immediate surgery. As if it was all predestined, Jordan received the precious little heart from Lukas when she was just 18 months old and was undergoing treatment in the same hospital where Lukas was hospitalized for an emergency rescue.

“When they said the heart was good, my instant reaction was that my daughter would get a second chance at life,” Gonzalez told TODAY. “But then on the flip side it took me about a second to realize that through our joy, another mother was grieving.”

Clark wanted to connect with the patient who received her son’s heart. After the successful transplant operation in 2013, Gonzalez left a message to Clark on Facebook, but unfortunately it remained buried in her Facebook inbox folder, unnoticed for more than two years.

It was only after two years that Clark discovered the important Facebook message from Jordan’s mom. Eventually, the two families soon connected and finally decided a time to meet at Phoenix Children’s Hospital. Clark traveled 5.5 hours from California to Arizona for this big day.

“I think I was more anxious than nervous,” Clark said. “Anxious to meet Jordan because she’s absolutely wonderful. I was nervous when I first got out of my car and walked up.”

But it turned out to be like meeting a family member. At the moment she and Jordan met, they ran toward each other and hugged.

“That’s your baby,” Gonzalez whispered, when Clark was tearfully listening to her dead son’s strongly beating heart inside Jordan’s chest.

“The sound was so strong,” Clark told the PEOPLE. “I could feel him there with me. He is continuing on through her, no doubt.”

“It’s indescribable,” she told TODAY. “So many different emotions in one—happy, sad, depressing, wonderful, proud. If all those words could be molded into one, that’s what it would be.”

Because of a mother’s compassionate heart, the tragedy has been turned into boundless happiness for another family. It forms an unbreakable bond between the two families as Jordan’s mother said, “We’re family now, we’re friends now, our families are families, we’ve brought our families together.”
