Winter Solstice reminds me of Hexagram 24 in I Ching, which goes by names including “Turning Back”, “Return”.
Hexagram 24 reminds us that when things reach their extreme, they have to turn back. For example, spring returns after a winter. This is the law of nature and not brought about by force. Likewise, when life is dark and tough and you have reached rock bottom, surely, life will only improve from then on.
Take heart of the natural cycle of life, life voyager!
