"When you analyse the face or body, which is beautiful for two days, after 10 years it's more difficult.
"It can eventually create a lot of unhappiness - that's nature."
So that incredibly shallow thing you're not supposed to say? What if, in fact, it's really deep?
The Dalai Lama said as a celibate monk he sublimated physical desire through "training of the mind" and intense analytical meditation.
True happiness, he said, came through peace of mind, altruism and compassion.
It's only not shallow if you think such things along with celibacy and lots of analysis.
