Dr. Wayne Dyer, the self-help guru and author of the bestselling 1976 book "Your Erroneous Zones," died Saturday night in Maui, Hawaii, at age 75.
"Wayne has left his body, passing away through the night," the Dyer family
wrote Sunday on Facebook. "He always said he couldn't wait for this next adventure to begin and had no fear of dying. Our hearts are broken, but we smile to think of how much our scurvy elephant will enjoy the other side."
Diagnosed with chronic lymphocytic leukemia in 2009, Dyer claimed that he treated himself with positive thinking, daily exercise, and so-called "psychic surgery" performed by Brazilian man João "John of God" Teixeira de Faria — a move seen as controversial by many.
According to Time magazine, Dyer was friends with many celebrities, including Oprah Winfrey. He also officiated the wedding of Ellen DeGeneres.
"It was always a pleasure to talk to @DrWayneWDyer about life's big questions," Winfrey wrote Sunday on Facebook. "He always had big answers. RIP Wayne. You brought the Light."
"Wayne Dyer has passed away today," wrote Dyer's fellow self-help guru Tony Robbins on Facebook. "4 those of us who loved him it's sad, but he knew death was a transition. We send love 4 his next adventure"
Dyer's most famous book, "Your Erroneous Zones," was based on the teachings of Siddha Yoga founder Krishna Rau, also known as Swami Muktananda.
NBC News reported that Dyer, often seen as a leader in the New Age spiritual movement, was "sometimes accused of appropriating and simplifying other thinkers' work for a general audience."
Dyer is survived by his eight children, as well as his third wife, from whom he was separated.
