According to Bauschatz in The Well and the Tree, Norns are not the same as the Moirae or Parcae.

Norns control not only individual occurrences but the whole course of human events.

Wyrd (and the Norns) govern the working out of the past into the present (or, more accurately, the working in of the present into the past).

The Tree is closely, but not directly, concerned with men.

The Tree is directly involved with the Aesir. The gods meet there every day.

Cycle of The Well and the Tree

The ‘falling’ of the dew reunites the waters from the tree with those of the well, into which the roots of the tree extend. The cyclic nature of this process with the well as both source and goal, beginning and ending of the nutritive process, combines all of the structural semantic elements of brunn, representing both an active, natural, welling source and a collecting, storing source. The myth presents a continuous cycle of activity.~ Bauschatz

You probably can’t. You know the month, the year, the day of the week. There is a clock on your wall or the dashboard of your car. You have a schedule, a calendar, a time for dinner or a movie. Yet all around you, timekeeping is ignored. Birds are not late. A dog does not check its watch. Deer do not fret over passing birthdays. Man alone measures time. Man alone chimes the hour. And, because of this, man alone suffers a paralyzing fear that no other creature endures. A fear of time running out.
