Radio and TV stations popularise Christmas by broadcasting Christmas carols and Christmas songs, including classical music such as the Hallelujah chorus from Handel's The Messiah.
Like many timeless carols, it speaks not just to the coming of Jesus Christ into a divided world, many years ago, but also of the relevance even today of the angel's message of peace and goodwill.
And of course, we have the Iranian mystic poet Rumi imploring us in ode after ode to get drunk and out of our minds so we can become blissfully present in the wow of now.
