She founded two nonprofits, The Nirvana Foundation for Psychic Research and the Society of Novus Spiritus, and was the author of dozens of books, many of which appeared on the New York Times Bestsellers list, according to the obituary.
Her 2009 book, "Temples on the Other Side," was intended to help people understand where they go after they die, she told Montel Williams.
"So you just don't float around," she said. "You can go to the Hall of Messengers, where you can talk to Jesus ... You can go to the Hall of Reconnection, where you can connect with someone you love."
In a statement included in the obituary on Browne's website, Williams called her a friend. "A beacon that shined for so many was extinguished today, but its brightness was relit and will now shine forever for many of us from above," he said.
Browne is survived by her husband, Michael Ulery, two sons and a sister, according to the obituary.
