good stories of asubha

may 2013,
heard story of thai monk (A.D.) who, as a layperson in college or high school, was about to call a girl he liked to ask her on a date. as he picked up phone, an image of a corpse came up and he hung up. He tried to dial again and once more a vivid image of a corpse popped up. So this would seem in a past life he practiced well and really took to heart the Buddha's teaching on samma vayamo #4, maintaining a kusala dhamma of a corpse.
