When we were young, we behaved in the way that hurt our parents, because we didn’t understand.
When we started a relationship, we behaved in the way that hurt the person in the relationship with us, because we didn’t understand.
When we started a family with children, we behaved in the way that hurt our children, because we didn’t understand.
When we live among the society and move around in the world, we behave in the way that hurt others in the society in the world, because we didn’t understand.
Above all, we constantly behaved in the way that hurt ourselves, because we didn’t understand.
Wittingly or unwittingly, we constantly hurt ourselves and others, regardless those whom we thought we love or hate, out of pride, self-identity, self-image, worldly ambitions, spiritual ambitions, desires of craving and aversion, likes and dislikes, disagreement, dissatisfaction, disappointment, anger, hatred, greed, jealousy, frustration, agitation, depression, grief, passionate love, lust, hurt, animosity, insecurity, doubt, discrimination, expectation, impatience, intolerance, humiliation, non-accommodating, ill-will, fear and worry, and etc.
If we still don’t understand, we will continue to hurt ourselves and everyone whom directly or indirectly coming in contact with us and the consequences of our ignorant selfish behavior, until the last breath of this life existence.
Accumulating all kinds of worldly knowledge in the world that allows us to be knowledgeable and skillful to be doing something in life and enhancing the quality of life, or creating/inventing something with higher technologies that is ecological or environmental friendly, also doesn’t guarantee that the mind is free from all these ignorance, egoism and impurities.
One naturally stops hurting oneself and other(s) upon the realization of purity (free from impurities), wisdom (free from ignorance), selflessness (free from egoism) and compassion (dispassionate unconditional love), regardless how much and what type of worldly knowledge one has been accumulating, good and bad condition of the world, pleasant and unpleasant life experiences, easy or difficult life condition, good and bad condition of the physical body, all kinds of mind perception of names and forms, achievements and non-achievements, and so on.
