Craft an evocative painting capturing the essence of Poson Poya in Sri Lanka. Depict a scenic landscape with distant mountains, prominently featuring Mihintale's sacred stone and the arrival of the Mihindu Rahats. Illustrate King Devanampiya Tissa placing his bow on the ground, gazing towards the stone, and subtly incorporate a deer nearby. Emphasize the spiritual significance and historical importance of this event in Sri Lankan Buddhism. Use a blend of warm colors to evoke a sense of reverence and historical depth, drawing inspiration from traditional representations of Poson Poya art
