" Now if we look at today’s materialistic life people seem mainly concerned with sensory experiences. So that’s why their satisfaction is very limited and brief, since their experience of happiness is so dependent on external stimuli. For example, so long as the music is playing, they feel happy.” He tilted his head to the side with a smile as if appreciating the music. “When something good is happening, they are happy. Good food, they are happy. When these things stop, then they feel bored, restless, and unhappy. Of course this is nothing new. Even in the time of the Buddha, people would fall into the trap of thinking that sensory experience would bring them happiness. "
