Who am I?

    That question -  Who am I? - is profoundly deep.  Of course I, like everyone else, asked that question between adolescence and adulthood, but perhaps I didn't succeed because I'm still asking that question.  Or, perhaps, we were never meant to settle that question completely once and for all.
    I remember at age 23, freshly graduated from college, hearing, "Seems you don't really know who you are."  These words came from a man I respected - after all he had a beard, wrinkles, married and studied along with me at a scaled-down seminary program.  I pondered his words a lot. What did he mean? Why did he say that?  How would I be different if I knew who I was?
    And now, my former high school English teacher who has kept in touch through the years and frequently invited me to meals and cultural events, insists that I am not - nor never was- an introvert.  If so, pah on Meyers Briggs psychological inventory which proclaimed me one, albeit a little known variety, a "social introvert," i.e. one who recoups by spending time alone, but to whom relationships are important.   
   Two other experts handed me differing definitions of introversion vs. extroversion this year.  One woman teacher and coach said, "You can tell the difference by the way each type processes.  I'm an extrovert, but my husband in an introvert.  So when I talk things out and propose an idea, my husband, being an introvert, thinks I'm earnest about doing what I've suggested  because he doesn't propose anything until he's already thought it through."
    I was excited about this definition at first and perhaps explaining it to my husband helped him understand that he can express enthusiasm for an idea I've expressed without committing himself, since I'm not committed yet.  Ideas like going to Alaska, going to live in France, etc.  But in practicality this definition hasn't found it entirely true. I process both ways, and so does my extremely introverted husband.
    Another expert, a psychologist friend, has blasted Meyers Briggs as being too simplistic and in other ways wanting.  He says that the amount of stimulation that an individual desires and thrives on indicates whether s/he is an introvert or an extrovert.  Not the degree of warmth which an individual exhibits and which is often taken as a sign of extroversion.  A person can come across to others as warm and still an introvert.  When I heard that, I thought, "That's me."
    Hmm . . . Perhaps I'm midway then in a scale of introversion vs. extroversion.
    I read today David's words, "Who am I, O Sovereign Lord..."  He then recounts the wonderful things God has done for him, such as taking him from following sheep around to being the king over a great people. I also feel like that.  I was once alone, hurt, fragile, embittered, insecure. I stayed away from much people contact because I was scared. Left me lonely, but safe.
    Oh, the wonderful things God has done for  me.  I am no longer who was was then, nor even who I was two years ago.  Theophostic Ministry (a type of healing prayer) is truly, deeply changing me the core of my being, from the inner depths to the outer indicators and actions.  According to TM's founder, Ed Smith, TM can change people's personalities, personalities are not a constant given as many have assumed or taught.   
    Ed Smith's point does seem true in my case.  I am no longer who I was.  So I ask again that age old question, "Who am I?"
