Nature uses its "sky canvas" not only during the day. :)
But at night it seems more mysterious, unknown, sometimes maybe even a bit spooky...
Though I love sunshine and brightness of the day, the night has its amazing charm and peacefulness, which I adore as much.
I guess we all need some balance - light and shadow, energy and relaxation - it's our own harmony, our private Tao in which we can define all Yins and Yangs, all aspects needed for our happiness and integrity.
Staring at the full moon in the quiet of the night can surely be one of them. :)
