"The Beggar and the Diamond" is a re-telling of a Hindu parable written by Stephen King which was published as part of his 1993 short story collection, Nightmares & Dreamscapes.
One day Ramu is walking along thinking about his unhappy existence and feeling angry at God.
God, at the request of an archangel who felt pity for the beggar, drops a massive diamond on his path in plain sight.
On the ground, Ramu has decided after some pondering that he should not be angry about his life or blame God because he still has a few things to be grateful for, such as retaining his sight at such an old age.
God takes back the diamond and puts an ironwood branch further up the path.
