Detach from the outcome
Don’t let your authentic and peaceful attitude depend on your relatives behaviour. As long as you remain connected to intention and radiate outwards the high energy, you’ve achieved your peace. It’s not your place or your purpose to make everyone else in your family think, feel, and believe as you do. The likelihood is great that you’ll see dramatic changes in your relatives as you teach them with your own persona how you intend to be treated. But if they don’t change, and if they continue their non peaceful ways, let go of your need to see them transformed. It all works in divine order, and the saying letting go and letting god is a helpful reminder for you. By letting go, you guarantee your own peace, and you dramatically increase the odds of helping others to do the same.
Affirm: I attract only peace into my life
Remind yourself of this affirmation many times on a give day particularly with your children and other more distant relatives. Also practice in grocery stores, when greeting flight attendants, when visiting the post office, and while driving your automobile. Say this silently to yourself as an absolute truth with unbending intent on my part, and it will work for you all the time. People will respond to you with smiles, acknowledgement, friendly gestures, and kind greetings all day long, remind yourself of the cogent observation, When you feel other than peaceful in any given moment with your family : I can choose peace, rather than this.
