"I read a couple of great books this year about human behavior, and this was one of the most interesting and profound. Both Jenn and John Doerr urged me to read it, and I’m glad I did. Everyone knows that a good night’s sleep is important—but what exactly counts as a good night’s sleep? And how do you make one happen?

"A living embodiment of Huxley’s Perennial Philosophy, Krishnamurti wrote many books about the need for modern people to wake up. As with Tagore, the horrors of World War II and the existential crisis of the Atomic Age dimmed Krishnamurti’s message, but he enjoyed a resurgence just before his death in 1986. He was sensationally glamorous to Westerners but relentless in confronting people with their lack of inner knowledge. The First and Last Freedom distills his teachings in a forceful, concentrated way. Few have taken such a stark view of the spiritual crisis in modern life."
