And so upon this wise I prayed -
Great Spirit, give to me
A heaven not so large as yours
But large enough for me. [ Emily Dickinson ]

To have prayed well is to have striven well.

The fountain of my heart dried up within me, -
With nought that loved me, and with nought to love,
I stood upon the desert earth alone.
And in that deep and utter agony,
Though then, then even most unfit to die
I fell upon my knees and prayed for death. [ Maturin ]

No man ever prayed heartily without learning something. [ Ralph Waldo Emerson ]

Vexed sailors curse the rain for which poor shepherds prayed in vain. [ Waller ]

Real knowledge, like every thing else of the highest value, is not to be obtained easily. It must be worked for, studied for, thought for, and, more than all, it must be prayed for. [ Thomas Arnold ]
