Material gratification is external, but happiness is internal. When monks talk about happiness, they tell the story of the musk deer, a tale derived from a poem by Kabir, a fifteenth-century Indian mystic and poet. The musk deer picks up an irresistible scent in the forest and chases it, searching for the source, not realizing that the scent comes from its own pores. It spends its whole life wandering fruitlessly. In the same way we search for happiness, finding it elusive, when it can be found within us.
