The world is beautiful. There is abundance. The body is well adapted to it. There is so much to do, learn and explore here. But then there are other people, with their huge Egos, they spoil all the fun. A lot of suffering is caused by retarded behaviour of others. In their ignorance and under the influence of wild Egoic tendencies, these people cause great harm and suffering. Sometimes a persons invites trouble by his own actions. Whatever is the cause, a majority of our suffering comes from others. Even seekers find themselves dealing with ignorant people who destroy their peace of mind routinely. Fortunately, one need not throw all those people out of the world, one can shield himself from their harmful effects. Realize that suffering is a state of mind, your own mind, and even if someone else is responsible for your messed up state of mind, you are fully capable of restoring it back to happiness. We all are free to do so, the choice is always there. This trick is called forgiving. It is useful when your suffering originates outside, usually from other people.
Forgiving is a mental action which is aimed at clearing negative programs. It is an action that results in non-action. Negative programs are mental structures that cause negative thoughts, desires and actions, which in turn lead to suffering and even more negative programs. This vicious circle continues. Negative or harmful programs are formed due to Egoic tendencies of anger, hate, envy, etc. The programs enforce these tendencies and cause more negative actions, and hence more suffering. Usually other people that are themselves under the influence of harmful programs are responsible for implanting those negative tendencies in their victims. In simple words, bad behaviour of bad people turns a person with otherwise healthy mind into a person full of mental afflictions and suffering. This happens because people are usually unconscious of their own tendencies and get easily influenced by other’s behaviour.
What is the cure? Forgive. The vicious circle needs to be broken at some point. One needs to do it by consciously terminating the programs or thoughts or actions. This needs to be done repeatedly because the mental structures are formed and strengthened via repetition and erasing them also requires repetition of corrective action. In simple words, not allowing and acting on the negative thoughts, which come up again and again, will slowly make the bad actions and suffering go away. This is the act of forgiving essentially.
