Best classic book – philosophy? An intro, for someone starting out I love Siddhartha by Herman Hesse. For someone who’s more advanced Jiddu Krishnamurti– I like his Total Freedom book. Osho’s–Great Challenge. Michael Singer’s–Untethered Soul. Marcus Aurelius–Meditations

If you could require the president to read one book, what would it be? “Meditations,” by Marcus Aurelius — Stoicism and the limitations of power. “When you wake up in the morning, tell yourself: The people I deal with today will be meddling, ungrateful, arrogant, dishonest, jealous and surly. They are like this because they can’t tell good from evil. But I have seen the beauty of good, and the ugliness of evil, and have recognized that the wrongdoer has a nature related to my own — not of the same blood or birth, but the same mind, and possessing a share of the divine.”
