Unitarian Universalism does not have a mystical tradition as far as I know and so it's adherents seek instruction in Self Actualization from other traditions leading to the hyphenated UU.
UU seems best organized to meet social and self esteem needs. If that is as far as it goes it will never become the World Class Religion that UUA President, Peter Morales, seems inspired to promote it to be.
However, I also find that the blogs Boston Unitarian and Monkey Mind do the point the way to an appreciation of a deeper tradition. BU imported from Christianity and Monkey Mind from Buddhism. As far as I can discern these two blogs are doing the best work around in deepening our UU tradition.
