Hi Frances,
I agree that these are deeper pd concepts. As far forgiving and letting go of resentments, I have the following suggestions:
1. Consider the two beliefs that people do the best they can given their level of consciousness at the time and that everything happens for a reason. This allows you
2. Do The Work of Byron Katie
http://thework.com/, Go through the website and watch the videos. Download the PDF worksheets and get crackin. With sustained effort, resentments vanish readily.
3. Something Steve talked about on his radio interview today was facing your negative feelings as they are. When you bring awareness to negative feelings instead of trying to avoid them, they tend to diminish on their own. This is best done throught journaling.
For being whole and complete on your own - it really comes down to your sense of self. This might require a lot of depth. Check out
Self-Acceptance vs. Personal Growth
I recommend reading through Eckhart Tolle's The Power of Now and A New Earth. You might also like The Six Pillars of Self-Esteem by Nathaniel Branden but I have mixed feelings about that book. Also, do The Work on anything that makes you feel incomplete as you are.
