The structure of the egg was once seen as analogous to the structure of the cosmos.
According to this theory, the eggshell was supposed to be the sky, the membrane inside the sky with clouds, the egg white symbolized water, and the egg yolk symbolized earth and minerals.
The harvesting of maple sap was accompanied by specific rituals.
The first day of the spring full moon was a harvest festival - that was when the Maple Dance was performed. Some tribes hold "maple moon" festivals to celebrate a return to old traditions.
