Sometimes it will seem like it is better to give up, give in and let your natural tendencies win.  You might not be able to figure out what the right thing to do really is.  When we struggle with anything we are trying to do it can leave us despondent and longing for an easy way out.  It is then that you have to shake off your perceived weakness and remember that you have a spark of the divine within you that has no weakness.   Your sorrow is sheer delusion with no more substance than you allow it to have.
