Although many faiths assign special significance to the full moon, it’s an exceptionally consequential day for Buddhists because many landmark events in the life of the Buddha took place on this day, or perhaps during the glistening moon washed nights. For starters, the Buddha was born on a full moon day. His renunciation took place on a full moon day. He attained Enlightenment, delivered his first sermon, and eventually passed on to Nibbana (or Nirvana) on full moon days. Personally, I find meditating under a full moon an exceptionally soothing and profound experience. Moonlight Meditation is pretty simple, and can be done by anyone, anywhere. It does not have to do with one’s religion or faith, it has to do with the power of nature.
It is believed, and confirmed by various studies that the moon exerts a considerable influence on humans. Passions and emotions get affected during full moon days and the word 'lunatic' is actually derived from the word 'lunar' (or moon) and indicates the influence the moon has on us. Some people find their ailments and mood swings aggravated during such periods. Research shows that certain phases of the moon not only affect humans and animals, but also influences plants and other elements. The most visible and undeniable impact is on water, especially low and high tides. Now, if the moon has this overpowering sway on water, then it could very well have it on our bodies as well, which after all, are hugely comprised of water.
