Sanctuaire sacré à l'intérieur d'un ancien arbre lumineux de nuit

A breathtaking, deeply serene fantasy artwork of a sacred sanctuary inside a hollow ancient bioluminescent tree. Soft warm floating paper lanterns cast a gentle golden glow over a quiet meditation rug surrounded by glowing lotus flowers. Outside the tree opening, a calm mirror-like lake reflects a starry purple galaxy night sky. Ethereal atmospheric mist, soothing dreamlike colors, rich mixed-media textures, masterclass composition, definition of Visual Impact and Relevance to Theme, 8k resolution, masterpiece.
