the old monk often took the young monk to the hill outside the temple to recite the lection.
one day the young monk said to the old monk,"how slowly the time goes!"
the old monk said,"you can have a try like this---in the morning sit to the west to read; and in the afternoon sit to the east to read."
at the master's advice, the young monk recited the lection against the sun. by and by he neglected the passage of time.
the next day he told the old monk ,"master, you're so masterly that i forget time with a switch of direction and absorb myself in the lection."
the old monk said,"whatever you do, only you leave time behind you can you focus on it selflessly."
