evidence: I’m reading author Gay Hendricks’ delightful detective series about Tenzing Norbu, a Tibetan Buddhist month turned LAPD robbery & homicide detective turned private investigator. Throughout his adventures, he uses his spiritual practices to calm anger, fear and confusion. In his fourth book, The Fourth Rule of Ten, Tenzing posits this rule: Let Go of Expectations – they always lead to suffering. And even old bard Shakespeare wrote, "Expectation is the root of all heartache."
