Put yourself in your mother’s shoes
It can be extremely easy to go with the flow of your emotions and not to understand the situation of your mother. You should think twice before you react and understand that there is no one in this world who loves you more than your mother. If you have done something which made your mother angry, then think deeply about your action and why your mother is not happy. Most probably, you will realise that she is angry for your own betterment and you will bring your relationship back to normal terms.
You must never let your ego come in your relationship with your mother. After a quarrel with your mother, you need to objectively assess the situation. Even if you come to a conclusion that your mother is at fault, you should still apologise to her.
Know the value of your mother
If you are not having good terms with your mother, you need to make yourself realise her importance in your life. Go through all the wonderful memories you have shared since childhood. Without your mother, you would not have existed.
Every religion puts a lot of emphasis on a person’s relationship with his/her mother. Therefore, you should follow the teachings of your religion and respect your mother more than anyone else. If you follow your religion, you will know that your mother is one of God's blessings.
Go and hug her
If you do not know how to end bitterness in your relation, just go to your mother and hug her. You do not need words to communicate your feelings to your mother, just a simple hug can do wonders.
