It's the cornerstone of creation. From the largest to the smallest. From the micro to the macro and everything in between.
The Micro Each cell of your body works in perfect harmony and balance. Although the cell in your optic nerve will never meet your liver cell, they exist in perfect balance. Each functioning in harmony. Only when things get out of balance is it termed dis-ease.
The Macro We live, move and have our being on a small planet orbiting an average star. Revolving in a galaxy along with hundreds of billions of other stars. It's an average galaxy. Moving through a universe containing billions of other galaxies. All moving at millions of miles per hour. Yet none of them moving too fast or too slow.
Amazingly, all happening automatically. From the micro to the macro, all in perfect balance. Without human guidance or intervention. As a matter of fact, it's only when 'we' get in the way do things tend to get out of balance.
So, to experience harmony and happiness, make sure you have balance in your life. Take time to smell the flowers. Tell someone you love them. It's worth the effort.
