The previous post reminded me of this poem by C S Lewis, where coldness becomes the symbol and experience of repentance.
After Prayers, Lie Cold
Arise my body, my small body, we have striven
Enough, and He is merciful; we are forgiven.
Arise small body, puppet-like and pale, and go,
White as the bed-clothes into bed, and cold as snow,
Undress with small, cold fingers and put out the light,
And be alone, hush'd mortal, in the sacred night,
-A meadow whipt flat with the rain, a cup
Emptied and clean, a garment washed and folded up,
Faded in colour, thinned almost to raggedness
By dirt and by the washing of that dirtiness.
Be not too quickly warm again. Lie cold; consent
To weariness' and pardon's watery element.
Drink up the bitter water, breathe the chilly death;
Soon enough comes the riot of our blood and breath.
C S Lewis
