The Princess of Wales has said her video series on nature has been "deeply personal" and has helped her "discover what it means to be alive".

In the final part of her quarterly Mother Nature project, posted on social media on her 44th birthday, Kate said the "coldest" and "darkest" season, winter, had a way of bringing "stillness, patience and quiet consideration".

"Where the stream slows just enough for us to see our own reflection," she added in the clip.

"To discover the deepest parts of ourselves. Alongside the whispers in the pulse of every living thing.

"I find myself reflecting on how deeply grateful I am.

"For the rivers within us flow with ease, fears washed away, cleanse and purify. Come to peace with our tears and discover what it means to be alive.

"To be at one with nature; a quiet teacher and a soft voice that guides.

"In memory. Helping us to heal."

The Kensington Palace video was accompanied by a personal post signed with a C, which read: "The Mother Nature series has been a deeply personal, creative reflection on how nature has helped me heal. But it is also a story about the power of nature and creativity in collective healing.

"There is so much we can learn from mother nature, as we look to build a happier, healthier world. C."

The princess's birthday on Friday falls just days before the first anniversary of her announcement at the start of 2025 that she was in remission from cancer.
