Compassion and empathy of others are the main antidotes. The challenge is to transform feelings of hatred and anger into positive emotions. One of the largest obstacle is to evaluate if these antidotes are practical. If you have examples of a situation which either approach was used and it’s outcomes, it will help. You can perform your personal experiment. Also, you can reflect on true past events which each approach was used. Similarly, you can create a mental example were the outcomes could be predicted based on both attitudes. If you do not see the practical uses of these emotional antidotes, you are not going to use them. If you feel that you are not capable of handling your emotions then, you are not going to try or give up at any sign of failure. What you think or believe is critical to what you do or not do. Another obstacle is the capacity to differentiate what is real from what is not real. How much of your perspective is based on reality and how much is based on fantasies, wishes or desires. Deeply rooted hatred and anger are usually associated with the self. In other words, these negative emotions are seen by you as essential attributes or yourself. Transforming them will require a new definition of yourself. This transformation is a real struggle because you have invested a lot of time and effort in keeping this premise. You see these emotions as fundamental aspects of reality. In other words, you believe that these emotions are part and essential components of the manifestation of God or good.
