There are two kinds. There is the DayTime kind, which is bright and welcoming and then there is the NightTime kind, which should never be confused. NightTime is dark and deep and may take you to unexpected places, places that the DayTime cannot. Things take time in the NightTime, they slow down and you can pause (you must, actually) and investigate carefully to find that level of objective detachment that is only possible under the spell of the NightTime. Seek the Day, but fear not the Night.
