Version

 As you grow spiritually you develop better versions of yourself.  One version improves on another in a sort of progression.  I am not sure that one ever arrives at the final real you.  But one can lose their best version so far, by ceasing to do, practice, and even to be open to new information about a practice.  Science can help a lot as it continues to discover new realities they never knew existed.  Just because we “know” something does not mean that what we know is the ultimate.  It is what the mind can hold at the moment.  So keep at it day by day.  Practice is just that, practice.  It means not perfect.
