Both full and new moon days are observed as yoga holidays in the Ashtanga Yoga tradition. What is the reasoning behind this?
Like all things of a watery nature (human beings are about 70% water), we are affected by the phases of the moon. The phases of the moon are determined by the moon’s relative position to the sun. Full moons occur when they are in opposition and new moons when they are in conjunction. Both sun and the moon exert a gravitational pull on the earth. Their relative positions create different energetic experiences that can be compared to the breath cycle. The full moon energy corresponds to the end of inhalation when the force of prana is greatest. This is an expansive, upward moving force that makes us feel energetic and emotional, but not well grounded. The Upanishads state that the main prana lives in the head. During the full moon we tend to be more headstrong.
The new moon energy corresponds to the end of exhalation when the force of apana is greatest. Apana is a contracting, downward moving force that makes us feel calm and grounded, but dense and disinclined towards physical exertion.
The Farmers Almanac recommends planting seeds at the new moon when the rooting force is strongest and transplanting at the full moon when the flowering force is strongest. Practicing Ashtanga Yoga over time makes us more attuned to natural cycles. Observing moon days is one way to recognize and honour the rhythms of nature so we can live in greater harmony with it.
Why We Don’t Practice on Moon Days
It has always been the tradition in Ashtanga Yoga to rest from asana practice on new and full moon days (tithis). When asked why we shouldn’t practice on these days, Guruji was fond of saying, “Two ‘planets’ [grahas] one place, very dangerous.” What is meant by this is that on these days, the sun and the moon are in a line relative to the position of the earth. Consequently, their gravitational forces are all combined, and thus the effect of the ‘planets’ more pronounced. One definitive effect of this is that the ocean’s tides are higher and lower on these days. When āsana practice is done daily, rest days are important for regeneration; and the extra biweekly ‘moon day’ comes as a welcomed respite.
Why do Jois Moon Days Sometimes Seem a Day Early?
We use an Indian astrology system of calculation (rather than a simple astronomy calculation). In this system, it is the period of time prior to the point the moon becomes exactly new/full that is considered as the ‘moon day’ (called a tithi in Indian Astrology). Further more, in this system, the day is considered to begin at sunrise rather than mid-night.
Further explanation: In India, where yoga comes from, the term ‘moon day’ is a loose translation of the Sanskrit term ‘tithi,’ and would be more accurately translated as ‘lunar phase’ rather than ‘moon day.’ Each tithi is the time period it takes for the the moon to traverse 12° in the sky thus making 30 tithis (or lunar phases) per lunar cycle. These tithis begin at varying times of day and actually vary in duration from approximately 19 to 26 hours. What loosely gets termed the full and new ‘moon days’ – from our teacher’s (Sharath Jois’) perspective – are actually the 15th and the 30th tithis of this Indian Astrology (Jyotish) system.
