* First rays: This refers to the first beams of sunlight appearing at dawn, when the sun is just starting to rise.

* Tiptoed: This implies the sun's rays are gently and quietly emerging, like someone carefully walking on their toes.

* Through the meadow: This shows the location of the sunrise – a field of grass, which suggests a peaceful and idyllic setting.

Overall meaning: The phrase evokes a sense of tranquility and beauty, suggesting the gentle arrival of a new day in a peaceful natural setting. It conveys the idea that dawn is a time of delicate beauty and quiet awakening.
