A friend's father passed on about 10 years ago. 3 years later, a child was born in the family. When the child was about 2-3 years old and very ill, my friend's mother took care of him. In his delirious state, the child suddenly called out to his grandmother (my friend's mother) by a pet name that only her long deceased husband would use on her. As the child grew, he could remember details pertaining to my friend's father long before my friend's time.
The child now no longer has any recollections.
Coincidence? Rebirth? We don't know...but it was kind of surreal.
To the topic starter...whatever anyone says will not (and should not) make you decide to accept something or not. If you are diligently practising, the truth will verify itself
