Create a black and white watercolor illustration capturing the essence of a story set in an ancient monastery nestled amidst the snow-capped peaks of the himalayas. the focal point should be a mysterious labyrinth known to have a thousand doors. within this intricate maze, depict a young monk named palden, looking both curious and overwhelmed by the countless doors and passages. in one serene corner of the labyrinth, illustrate palden seated in deep meditation, with the ethereal figure of an old nun named dechen appearing before him, offering wisdom. the overall mood should be one of mystery, introspection, and enlightenment. the labyrinth's design should subtly hint at life's journey, emphasizing the twists, turns, and discoveries along the way.
