What is the key to happiness?

There is such a thing as a single recipe for perfect balance without worrying about details.  Whatever your circumstances you can please all the doshas by doing just one simple thing: follow a nature-friendly routine not dissimilar to our ancestors.   What is a "nature-friendly" routine?  It is a routine that imitates natures daily and seasonal rhythm.  Day-night, spring-summer-fall-winter, birth-death.  The ancient sages saw in that rhythm more than a pattern, they found it was the key to happiness here on earth. Don't worry, be happy!!
