1) Always remember you are a SOUL on a journey. Therefore, you must acknowledge that your emotions and feelings come from your ego and personality and never from your Soul.
2) Know that emotions are most certainly the ingredients and foundation for every Soul's life experiences and development.
3) The solution is forgiveness and compassion for both yourself and others who have "triggered" your negative reactions and feelings.
4) You must constantly observe and be aware of your emotions and always work at controlling your reactions and thoughts in a given situation. Remember to change old and negative patterns.
5) You also need to understand that it is "HOW" you tackle or cope with circumstances in your life that counts for your spiritual development and not "WHY" or "WHEREFORE" things happen to you.
6) Finally accepting and knowing that forgiveness and letting go of all negative feelings, emotions and thoughts is the only way forward.
