Ray stands at the center of a criminal investigation into three deaths at an Arizona sweat lodge earlier this month.
"I saw an ego just blow up," Mickey Reynolds, a former associate of Ray's, told CBS' "The Early Show" Monday.
Reynolds said he funneled several followers to Ray. "I never really checked into his credentials," Reynolds said. "I just believed him."
When Ray appeared in film "The Secret," his income was $1.5 million. Then came Oprah Winfrey, who featured Ray and the secrets of other new age experts on her
Show - sales soared, as did Ray's personal fortune. His revenue topped $9 million last year, CBS News correspondent Sandra Hughes reports.
The deadly sweat lodge ceremony was part of Ray's "spiritual warrior" retreat. Each participant paid $9,000, but a survivor says that as people died and others passed out, ray abandoned them.
Dr. Beverly Bunn told "The Early Show" recently.
Ray later posted condolences on his Facebook page and is continuing with his workshops, even as authorities have declared the deaths homicides, Hughes reports.
"I'm sure that investigators and prosecutors feel that this motivates them all the more, to go after him," CBS News legal analyst Lisa Bloom said.
Investigators in Arizona would like to hear from Ray as well. He has yet to file a statement or offer his account of the tragedy.
