How do you
undo a habit?  Choose differently, over
and over.  This requires conscious
attention constantly.  Spiritual awakening
does not happen by itself, nor does changing thoughts and behaviors which no
longer fit the growing soul.  Once awakened,
place attention on what is happening with the ego.  Find yourself a reminder.  When a trigger causes a habitual response
emotionally, stop yourself as the awakened spirit that you are and choose a
different reaction over and over until it becomes a new habit.  While you are at it, go back and look at the
root of your habitual reaction.  What was
the root cause?  Pull it out gently by
the root and see it dissolving.  Now you
are no longer creating karma, but helping to erase it so that your true nature
can shine.
