Hold no grudges, and practice forgiveness
The key to having peace in all your family relationships is forgiveness. Your relatives are simply doing what they’ve been taught to do over a lifetime, and the lifetimes of many of their ancestors. Shower them with understanding and forgiveness from your heart.
This passage offers so much in the fulfilment of this intention
Do you want peace? Forgiveness offers it.
Do you want happiness, a quiet mind,
a certainty of purpose,
and a sense of worth and beauty
that transcends the world?
Do you want a quietness that cannot be disturbed,
a gentleness that can never be hurt,
a deep abiding comfort,
and a rest so perfect it can never be upset?
All this forgives offers you.
Be in a state of gratitude
Rather than being in a state of non-peace concerning any family members, say a prayer of gratitude for their presence in your life and all that they have come to teach you. As you work towards the absolute knowing that this intention will manifest for you, remind yourself on a daily basis that you can never remedy a bad relationship by condemning it.
