Blame disempowers, handicaps, and discourages you. Thus, it prevents you from realizing how you created the situation and how you can improve it. Blame is to deny karma, to deny your responsibility in a cause and effect relationship.
Karma
Beliefs
When something keeps repeating itself in your life, it’s usually because of a belief you are not aware of.
— Mahatma Das
The Golden Law of Karma
How you treat others determines how much happiness or suffering you will experience.
— Mahatma Das
Karma is your teacher
Do not blame the agent of your karma. The people who hurt you are your teachers. They bring you invaluable lessons.
