I listened to this as an audio book. As my husband says, Thich Nhat Hanh could read the phone book and his voice alone would make it a worthwhile listen.
I respect him as someone who has known and witnessed real and deep suffering -- the mere fact that he can speak about happiness (or love or liberation) is a testimony in and of itself. The fact that he does so convincingly, humbly and with humor is amazing. I do love his wry humor -- "If you go to get a passport, you cannot say, 'I belong to the realm of no both and no death.' You must produce a birth certificate."" or "I think, therefore I am not here."
I cannot claim to truly grasp some of the Buddhist notions of non-being and non-personhood, but I am nonetheless taken by much of what he teaches (and lives.) Speaking of which, visit the Plum Village web site and read about his response to his slow recovery from his recent stroke. He's a transformative spiritual leader.
