Natural Cycles

In christian practices, the liturgical year, and the liturgy of the hours were organized in relation with the cosmic cycles of day and night as well as the seasons and their impact on human beings. For instance, mystagogy happened during the night offices, and rituals were coordinated with events like sunrise and sunset in complex ways.

This is true of many other traditions.

We know there are more deaths during full moons, with moon cycles having various other effects, including changing the quality of trees's wood, and so we can assume there are other effects on humans. There are also more death and stress in the winter. All of these things are potential riggers for spontaneous Emergent Phenomena, and it is no surprise that many Traditions include the natural cycles in their rituals, symbolism, and practices.
