Today, in the Northern Hemisphere, it’s Winter Solstice, a day variously to reflect on the past year, to celebrate the season’s turning from darkness towards the light of the coming summer, and to draw together in the warmth we humans have learned to make against the long cold. It is tempting to locate its origins in the Last Glacial Maximum, when our ancestors must have been so acutely aware of their fragility in the face of the huge weight of time and climate that bore down on them, and sought with such longing for an assurance of this turning season.

Today is also the day the United Nations has set aside as World Meditation Day, celebrated for the first time this year. (Jochen Weber, writing for the Secular Buddhist Network, has an excellent and well-linked reflection on their website.)

Meditation, as far as we can tell from historical research, has been practised in something like its present form for at least 5000 years; the Winter Solstice has been celebrated, in ways we can recognise, at Neolithic sites like Newgrange and Slieve Gullion for roughly the same length of time.

To sit still in winter, to wait for the season’s turning, to watch for the coming of the light, must be one of the deepest instincts of humanity, going far back into the beginnings of our species, perhaps even of our old, old relatives from before we modern humans appeared. Sitting in my warm, lamplit room this evening I felt for a moment part of all this, no different from the long succession of humankind whose DNA still sings in my own blood; and something in me was thankful, in a way I hadn’t imagined, for warmth and life, and for the sweet succession of generations of women and men who have watched, just as I do, for the light.
