The Duke and Duchess of Sussex urged people to share their stories about acts of compassion. Harry and Meghan said that compassion "means more than the dictionary definition".
The couple, who are living in California after quitting royal duties, added: "It means listening with open ears to the suffering and celebrations of communities and people beyond ourselves.
"It means taking the time to understand their perspectives, experiences and needs based on what they say, rather than assuming what they need."
Harry and Meghan's comments could be seen to have a hidden message for the royals.
In their controversial Oprah Winfrey interview, Meghan said she was not listened to by the monarchy when she was left suicidal by online trolling.
She said: "I went to the institution, and I said that I needed to go somewhere to get help.
"I said that, ‘I’ve never felt this way before, and I need to go somewhere’.
"And I was told that I couldn’t, that it wouldn’t be good for the institution."
Asked if he would have told other members of the Royal Family that Meghan needed help, Harry said: "That’s just not a conversation that would be had."
The Duke of Sussex also accused the royals of "total neglect" in his Apple TV documentary series, The Me You Can't See.
