Science behind Ekadashi:
The moon controls the water on Earth, so it is believed that the moon controls the water in our body as well.
"Interestingly, the word “menstruation” is related to the word “moon.” The word “menstruation” and "menses” are derived from the Latin word mensis, which means month, which is also linked to the Greek word, mene, meaning moon."
"Dr. Lieber further states, “ Because of complex interplay between hormonal balance and fluid and electrolyte balance, women at certain times during the menstrual cycle may be more susceptible to the triggering effects of biological tides. During prementruum, many women experience bloating, tension, and irritability. Transient fluid buildups and electrolyte imbalance occur. The added physiological stress of a biological high tide occurring during prementruum could result in drastic physical and /or behavioural consequences."
The Ekadashi day is recognized as the best of all days to fast because compared to any other days of the moon cycle, the athmosperic pressure is the lowest on the Ekadashi days. Therefore this is the best time to fast and cleanse the bowel system.
Anmerkung:
Je nachdem, wie Sonne, Mond und Erde zueinander positioniert sind, verstärkt die Sonne die Gezeiten oder schwächt sie ab. Besonders wichtig sind die beiden Konstellationen, bei denen alle drei Himmelskörper auf einer Linie stehen, also Neu- und Vollmond. Dann verstärken sich die Gezeitenwirkungen von Sonne und Mond, und es kommt zu einer besonders hohen Flut und einer besonders niedrigen Ebbe. Bei Halbmond hingegen gleichen sich beide Einflüsse zum Teil aus. Es kommt zu einer nur schwach ausgeprägter Flut und Ebbe.
