When the light of the sun of this day shines into the inner chamber of Sliabh na Calli (The Cailleach’s mound). By solar reckoning, the year is exactly half. Half day, half night. At one exact moment, the world balanced on a pin head. Everything in equal measure, fifty-fifty, resting in perfect balance, a pause. A breath. Exhale. The cry of the cuckoo calls out. Release. We move on to the lighter times. The spring equinox La na Cailleach is here.
