The psychologist Abraham Maslow said that man really needs just a few things for peace and happiness ... a certain amount of food and a healthy environment, shelter and physical safety, the love and friendship of others. Beyond that, anything else might be seen as a luxury! What is more, we can be prisoners of "things" if we crave them to excess, hang our happiness on them, run after them, hoard them, cling to them. Thus, we should learn the freedom of a Zen monk, who finds the whole universe in a small, nearly empty room ... who has few possessions, and is not very much attached to even those.
It is hard to do these days for most of us in the west (me too), but there is great good in not running after or being tied to material things.
