The amusements that we play as youths familiarize us with the feeling of losing. It makes us understand that in this present reality, you win at specific times furthermore lose as well. We grow up knowing that losing and winning is a part of life.
Regardless of how terrible we feel we still face the feeling of loss from time to time. As we turn out to get older and are gone up against with win-lose circumstances in life, we get by with it. However, on some occasions, the monster inside us appears when we discover that that at one point the game were "not fair". When people whom we trust or love cheat us, we are emotionally hurt and its impact to us is unbearable. Our instincts quickly tell us to get revenge as we recover from the nonexistent knifes that stabbed us.
Regardless of how justified we think our search for revenge is, it is never an answer. "Retribution" is a reaction. Any response will undoubtedly have grave outcomes in the material world as well as the ethereal world. As the great philosopher Confucius was once quoted:
“Before you embark on a journey of revenge, dig two graves.”
Confucius meant something similar to how karma works. Whenever we decide to take revenge we must be prepared for the consequences of our act and intentions.
The best approach in these painful times of our lives lies on the quest for justice. By seeking for justice, we react to our circumstance in the most humanly path conceivable with agreement to the law or "dharma". It doesn't mean we are simply permitting such circumstances in our lives and call it as 'fate'. If we do get justice in this world, we ought to be thankful, yet on specific results that we don't, we need to understand that no matter the how much time it takes, the universe offers revenge through the supreme Law of Karma.
