Where any-angled light would congregate

I like that Philip Larkin, who likened churchgoing to funereal tourism, can yet imagine a religion, can raise his glass to something infinite.

This is “Water.”

If I were called in
To construct a religion
I should make use of water.

Going to church
Would entail a fording
To dry, different clothes;

My liturgy would employ
Images of sousing,
A furious devout drench,

And I should raise in the east
A glass of water
Where any-angled light
Would congregate endlessly.
