Dr. Tessy Ojo, CEO of The Diana Award, tells PEOPLE that Prince William and Prince Harry mirror their mother, Princess Diana, and her ability to go “where the pain was.”

Prince Harry might be hard at work, but the royal is still prioritizing family, even when he can't be with them. Harry is currently away from his wife Meghan Markle and their two children, Archie and Lilibet,

Prince Harry has spoken about his mother Princess Diana's legacy as he attended an event in New York during his visit without Meghan Markle.

"My mother would have been horrified that anyone’s children or grandchildren would live in a world still infested with mines.”

Prince Harry is in New York for a busy few days of engagements related to his philanthropic endeavors, but the focus of his first full day in the city was clear, as he honored the legacy of his mother,

Your activism [and] your compassion are two things that are so true to how my mum lived her life and what she believed in,” he told the two recipients of the award.

He told Harry: "Prince Harry, thank you for your leadership, for your heart, for your vision, for sustaining the legacy of your mother and for inspiring a whole new generation around the world to be engaged in this critical work against the scourge of land mines.”
