SCHIZO WORLD OF ROBIN WILLIAMS

Even though ROBIN WILLIAMS quickly bounced back from scary open heart surgery and resumed his comedy concert tour, the wild-and-crazy 57-year-old - finally realizing it's live-stress-free-or-die time - came up with a genius idea:

Imitating the voice of an old Japanese yoga master he once knew, he created a character he calls "Haruki," and recorded calming messages programmed to play in his home every few minutes, stuff like: "Haruki say…remember always to be mellow, Mister Williams…" and, "Man with bad heart must eat only good food…!"

It sounds crazy, Robin told pals - but definitely works for him.
