Why We Observe Moon Days
The moon's gravitational pull affects Earth's tides, and because humans are largely composed of water (around 70%), it is believed that these forces also impact our bodies. This gravitational influence is stronger during both full and new moon phases.
Full Moon
Corresponds to the end of inhalation, when prana—an expansive, upward-moving force—is strongest. This can make us feel more energetic but also potentially ungrounded, increasing the risk of injury.
New Moon
Corresponds to the end of exhalation, when apana—a contracting, downward-moving force—is strongest. This can lead to feelings of being grounded and calm, but also lethargic and dense.
Observing moon days is a way to honor the teachings and lineage, tune into natural rhythms, and give the body essential time to recover and rejuvenate.
