An interesting excerpt from excerpt from Lama Zopa Rinpoche and Lama Yeshe’s Teaching from Tibet:
When you look at materialistic societies and the way people live, your own mind gets disturbed. The people there are increasingly busy, and new and different problems continually arise; they’re tense and nervous and have no time to relax. In India, you see people relaxing all over the place, but in the West, you pick up the vibration of the population’s agitated minds and finish up feeling nervous yourself. If happiness depended solely on external development, countries like Switzerland and America would be the most peaceful places on earth, with less quarreling, fighting and violence, but they’re not like that.
