Wayne Dyer, the author who turned his 1976 best-seller “Your Erroneous Zones” into a self-help empire, died Saturday in Maui, Hawaii, his publisher and family reported via Facebook. He was 75.

The cause of death was not disclosed.

In 2009, Dyer was diagnosed with chronic lymphocytic leukemia but he claimed to have treated the disease with positive thinking, daily workouts and “psychic surgery” by the Brazilian spiritualist João Teixeira de Faria.

Dyer, a psychotherapist and former professor at St. John’s University in New York, was a friend and frequent guest of Oprah Winfrey, appearing on her show many times over the years.

The former daily talk-show host and head of the OWN network tweeted a tribute to Dyer on Sunday night:

Ellen DeGeneres, another longtime fan of Dyer’s, offered her own tribute, complete with a photo from her 2008 wedding to actress Portia De Rossi.  

In more than 30 books, including “The Power of Intention” and “Stop the Excuses! How to Change Lifelong Thoughts,” Dyer espoused a philosophy that positive, happy thoughts can lead to a positive, happy life.
