In an Instagram post on Dec. 27, Dayle’s daughter, Ryan Haddon, remembered her mother with a lengthy tribute. She shared a selection of photos of her mom’s magazine covers, as well as some of the Canadian-born model working as an ambassador for the humanitarian aid organization UNICEF.
“The bright light that is Dayle has dimmed in this Earthly realm. Shining somewhere as radiantly as ever where it’s most needed, I have no doubt,” Ryan began.
“She was a woman in her power, yet soft and attentive to all. Deeply creative and curious, gifted with beauty inside and out. Always kind and thoughtful,” she continued of her famous mother. “In conversation, she could go to the deepest of places and also soar the highest heights of spiritual understanding. She held so many up, saw their greatness sometimes hidden to them, and always built bridges with her own connections to help them ascend. She was everyone’s greatest champion. An inspiration to many.”

“I always trust the timing of things,” Ryan added in her Instagram caption. “There are no accidents and certainly how we enter and exit this world is mystical and unknowable. She was a high-hearted spiritual being that put value on her soul’s evolution, so I know her journey here in this dimension must have been complete.
“I honor her. I bow to her. I revere all the paths and adventures taken. I saw her be golden and always reach for the Light in all areas of her life,” she concluded. “Thank you everyone who was a part of her journey that helped to shape her, enrich her and activate her to become the absolute gem that she is. She loved so many.”
“A pure heart. A rich inner life. Touching so many lives. A life well lived. Rest in Light, Mom,” Ryan signed her heartfelt tribute.
