Create an image of Lord Shiva, the revered Hindu deity, gracefully seated in deep meditation on a lofty mountaintop. His presence is awe-inspiring and divine, radiating an inner glow that signifies his celestial power. Envelop him with ethereal mists and towering snow-capped peaks, highlighting the tranquil yet mighty aura of the landscape. Capture Shiva's divine energy and omnipotence, symbolizing his mastery over the cosmic elements. A serpent coils around his neck, and his serene countenance reflects wisdom and strength. The scene should inspire reverence and wonder, portraying Shiva as the ultimate deity reigning over the sacred mountain realm.
