No, we do not turn colors. Instead we deepen our richness as individuals in adulthood. This becomes our color. Our energies that were so vibrant and wild in our youth become more mellowed or, perhaps, merely more focused. We become intimately aware that our time on earth is limited and we endeavor to make the most of it.
All seasons have their own beauty and function.
Without spring, there would be no new growth. Without summer, the growth from spring would not ripen and mature. Without autumn, there would be no harvest. Without winter, there would be no preparation for the spring's new growth. And so it goes, year after year.
