According to Celtic teaching, on the night halfway between the fall equinox and the winter solstice, the veil between the world of the dead and the world of the living lifts, and spirits wander among us. Separate from but similar to the traditions of Día de las Muertos and All Souls / All Saints, this tradition (All Hallows Eve / Samhain) points us to the mysterious connection that binds us through time and love. This will be a Unitarian Universalist apologia for the mystic heart.
