Does’nt interst me much. While some cases may be genuine, one must beware of fraud. And of diabolical phenomena. Just be careful, don’t get too involved in any unapproved phenomena.
There’s a reason why the Church is slow to approve any such occurences. Fraud etc. There was a 17th century stigmatist who was revered as a Saint by the people where she lived. She became very ill, and confessed she got the stigmata from the devil. She recovered and was sent away to a convent. Thre she remained until death. So not all are genuine.
Many statues are carefully designed to weep etc. So be careful. I don’t deny that such supernatural occurences happen. Just be cautious.
