Original text: "Words of the Sun"

Open your windows

Open your doors

Let me in, let I go in

Into your hut

I bring a golden bouquet

I bring the fragrance of the forest

Get up quickly, get up quickly

Raise your head from the pillow

Let your eyes see my arrival

Let your hearts be like small wooden houses

Open their windows that have been closed for a long time

Let me fill the space of your hearts with bouquets, fragrance, light,

warmth and dew
