During our journey there were two occasions that we celebrated by honoring someone's talent. Everyone is recognized by a special party, but it has nothing to do with age or birthdate - it is in recognition of uniqueness and contribution to life. They believe that the purpose for the passage of time is to allow a person to become better, wiser, to express more and more of one's beingness. So if you are a better person this year than last, and only you know that for certain, then you call for a party. When you say you are ready, everyone honors that.
