May the blessing of light be on you,
light outside, light inside.
May the blessed sunlight shine upon you
and warm your heart till it glows
like a great fire, so that the stranger
may be warmed at it, as well as the friend.
And may the light shine upon your eyes
like a candle set in the window,
bidding the wanderer in out of the storm.
If the heart wanders or is distracted, bring it back to the point quite gently... And even if you did nothing during the whole of your hour but bring your heart back, though it went away every time you brought it back, your hour would be very well employed.
