(Religious) morality can sometimes get in the way of spirituality by focusing on WHAT is being done rather than on WHO is doing. Mortality concerns itself with the actions and thoughts of presumably ‘known’ selves; spirituality focuses more on the mysterious underlying ‘Self’ that may or may not be ‘responsible’ for such actions.
This shift of focus may partly explain why certain types of action e.g. alcoholism or sexual promiscuity may be judged differently (e.g. more ‘leniently’) when engaged in by ‘spiritual’ teachers than by more traditional ‘religious’ teachers.
