After listening to Dalai Lama's speech, I realized how hard it is to be become truely buddhist monk free of greed, jealousy, and anger. Dalai Lama himself said that still he has anger, jealousy inside him surfacing now and then.. example given was how he felt jealous when the other translator could speak beautiful english. But true monks would never make such comment for himself. because true monks are already free of such bad qualities.... So practicing is good always... but very hard to achieve nirvana.. that's what Dalai proved in that speech.
