This is not a hearsay but the person directly involved (the
piano teacher) told me her father's story.
My nephew's piano teacher comes from a Christian family, her
father was a Christian since young. After her father passed away
(more than 49 days), she saw her father's spirit in her house.
Luckily one of her mother's friend who is a Buddhist advised them
to chao du. One night, she saw a ray of bright light flowing out
from her house. Since then, she did not see her father's spirit.
She and her mother are Buddhists now.
I believed her story because there is no reason for a Christian
to tell me this kind of story.
Her late father is in heaven now....blessed and will be taking
care of the family.
