Samhain

Samhain was considered to be a moment when the veil between this world and the otherworld was at its thinnest...This was a liminal moment in the calendar, a time between two worlds, between two phases of the year, when worshippers were about to cross a boundary but hadn't yet done so. Samhain was a way of marking that ambiguous moment when you didn't know who you were about to become, or what the future would hold. It was a celebration of limbo.

Winter is not the death of the life cycle

Plants and animals don't fight the winter; they don't pretend it's not happening and attempt to carry on living the same lives that they lived in the summer. They prepare. They adapt. They perform extraordinary acts of metamorphosis to get them through. Winter is a time of withdrawing from the world, maximising scant resources, carrying out acts of brutal efficiency and vanishing from sight; but that's where the transformation occurs. Winter is not the death of the life cycle, but its crucible.
