The following quote by the great preacher, Bishop and pre-eminent poet John Donne, confesses his ease of distraction during prayer.
"I throw myself down in my Chamber, and I call in, and invite God, and his Angels thither, and when they are there, I neglect God and his Angels, for the noise of a fly, for the rattling of a coach, for the whining of a door…
A memory of yesterday’s pleasures, a fear of tomorrow’s dangers, a straw under my knee, a noise in mine ear, a light in mine eye, an anything, a nothing, a fancy, a Chimera in my brain, troubles me in my prayer. So certainly is there nothing, nothing in spiritual things, perfect in this world."
John Donne (1572-1631)
