Hedge fund billionaire Ray Dalio: Meditation is ‘the single most important reason' for my success

"It is certainly the greatest gift I can give anyone," Dalio, 68, writes on Facebook.

Dalio says in his book "Principles" that he learned the practice after the Beatles famously studied Transcendental Meditation in India in 1968. It allows him to think more clearly and creatively, he says.

"It helps slow things down so that I can act calmly, even in the face of chaos, just like a ninja in a street fight," Dalio writes.

In his Facebook post, Dalio, currently worth almost $18 billion according to Forbes, cites author and meditation teacher Bob Roth as "the best expert/teacher on it I know" and recommends Roth's new book, "Strength in Stillness: The Power of Transcendental Meditation."
