“The bright light that is Dayle has dimmed in this earthly realm. I have no doubt will shine as brightly as ever where it is most needed,” Ryan began.

“She was a woman in her power, yet soft and attentive to everyone. 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 places and also soar to the highest heights of spiritual understanding. She held up so many, seeing their greatness sometimes hidden from them, always building bridges with her own connections to help them up. She was everyone’s greatest champion.

“I always trust the timing of things,” Ryan added in his Instagram caption. “There are no accidents, and it is certainly how we enter and exit this world, mysterious and ignorant. She was a high-hearted spiritual being who valued the development of her soul, so I know that her journey here in this dimension must have been complete.

“I honor her. I bow to her. I honor all the paths and adventures I have taken. I saw her being golden and always reaching for the Light in all areas of her life,” she concluded. “Thank you to everyone who was a part of her journey, who helped shape her, enrich her and enable her to become the absolute gem that she is. She was loved by so many.”

“A pure heart. A rich inner life. Touching so many lives. A life well lived. Rest in the light, Mom,” Ryan captioned his heartfelt tribute.
