I believe that when I have experienced mania induced psychosis my worldview has expanded to include a "glimpse behind the curtain" of the spiritual world.  Perhaps the way my mind (and apparently the minds of many others) is wired has allowed these short looks into an expanded consciousness/reality.  I do find it extremely initeresting that as I research spirituality and read both new age and ancient mystic writers that they all describe feelings and experiences that are almost a perfect match to what I have been through.  The loss of ego, the feeling of interconnectedness  with everything, intense feelings of euphoria/love, and grandiose ideas of wanting to be a "messiah" of sorts and help others to experience what I was.  To me my bipolar disorder is both a blessing and a curse but I look at it as more of a blessing.  If total "sanity" meant that I wouldn't get to feel and experience what I had (did I mention the mind blowing synchronicities that even my rational friends and family were forced to admit were definitely going on around me at the time) then I don't want it.  I'd rather have my different view of reality, even if it means that "coming down from the mountain" is painful then never to have seen what I have.  If what I've said makes any sense to you at all I hope you keep looking for your answers safely.  Remember that your Doctor's were put into your life by God for a reason as well!
