Almost every single year, at least one article comes out about crowds seeing a Ganesh statue in India drinking milk or Catholics seeing Mary ( or Jesus ) statues bleed, cry........or seeing their images in toast? Why don't Catholics see Ganesh images in their toast or why don't Hindus see Jesus statues bleeding.
That is how they were inculcated by growing up in the culture where they were born.
This is probably a factor with Buddhist monks and nuns from foreign lands as well. They probably spent years meditating before getting past life memories. That is years of reading Buddhist beliefs, being around Buddhists and thinking Buddhism.
When I was in highschool I was very much into yoga and read a lot of things by yogis. This was a few decades ago, so I can't recall names, but I remember reading about some great Hindu teacher from the past being on record as warning people about religious visions and instructing people to ignore them, as he realized the mind sees what it or other people train it to see.
Dr. Stevenson tried to turn that argument onto its head to explain why so many of his case studies came from Asian children and so few from the West.
I don't buy that. I grew up in the west. I can't recall anyone every discouraging a young child about rebirth/reincarnation.......or even mentioning it. There isn't a reason for western toddlers not to be recalling past lives as much as Asian toddlers.
Even if you put all of that aside and look at westerners who spontaneously have memories of other lives and were never exposed to the concepts of reincarnation in any way shape or form, you still have a problem.
All you have is the "fact" that a person has memories from another person who died in the past ( lets assume this is all verified by records ). That doesn't mean there is rebirth, let alone rebirth as the Asian religions describe it, let alone all of the other tenents of Asian religions. All you have are memories which may have come from another source, like a Jungian racial memory. That theory and probably others are less wild than Hindu reincarnation of Buddhist rebirth.
In reading the scriptures, there are two kinds of mistakes:
One mistake is to cling to the literal text and miss the inner principles.
The second mistake is to recognize the principles but not apply them to your own mind, so that you waste time and just make them into causes of entanglement.
