How Yin and Yang Shift Throughout a Day

yin -yang-cooling, warming cycleYang is the warming cycle, Yin is the cooling cycle.

The movement of light and dark throughout a twenty-four hour period is the motion of Yin and Yang expanding and contracting, flowing, one into the other in an endless dance.


Observing the small nuances of these changes is a simple and profound learning experience. Particularly observe the peak changes of sunrise, noon, sunset, and midnight. Explore with every sense the changes in light, temperature, activity, sound, smell, and energy. Even if you are in a busy city, just pause and notice.

Direct Observation

Leave the lights off and watch the day pass into the night, or the light returning in the morning. Observation of Nature is how the ancients learned the theory of Yin and Yang. We have that same opportunity every minute of the day and night.

    Thank you, Cindy, it’s always great to return to the Beginning and reflecting on the Taiji … seeing how Yin and Yang is reflected in our environment and within all our activities.

    I’ve been using my Reiki on the Meridian Points. I can’t believe on how I feel about combining the two while healing a person. It is the most amazing experience that I have ever been through. Thank you once a again for teaching those who want to know and master the art of healing others by the ALL NATURAL WAYS, and not by man made drugs that can still harm you in other ways. I really mean this…… May you be BLESSED in so many different ways…… A BIG, BIG THANK YOU

    I love the total silence that falls just before sunrise. The waiting stillness of it. Then hearing the dawn chorus that celebrates and welcomes the new day as the sun rises. Nature’s daily ritual that is part of the’endless dance’that we are sharing. My soul, and my day, always feels blessed each time I experience this ritual.

    Sometimes we just have to slow ourselves down and observe. Thank you for the reminder, Cindy
