A beautiful explanation on Karmic relationship by Vijay Reddy –

“The relationship that drives people crazy with anger and frustration are from a past life. These are the people who really get under your skin and exasperate you endlessly. Very often, these karmic relationships are with people in your immediate family.

Karmic relationships mean that you’ve had prior lifetimes with this person, and you both were sent back to be together to work things out peacefully. This was your soul’s choice, although it was probably highly pushed upon you by your guides and angels who helped you script out much of your life. Usually a karmic relationship is someone with whom you had a battle or other harsh circumstances. You returned together in this lifetime to ensure that you’d work things out, and clear both of your energies.

If you don’t clear the energies in this lifetime, you’ll be pressured to continue to incarnate with this soul again and again and again.

And each lifetime, his or her relationship to you will continue to be close, either through genetics and familial bonds, or through friendship, marriage, or career. So, that annoying co-worker could be your mother or husband next lifetime unless you clear the energy with her in this one.

You’re brought together with the other soul so that you can forgive him or her. This doesn’t mean forgiving their actions. It means detoxing your soul by releasing anger toward them. You don’t have to hang out with the person, but you do need to release old pent-up toxic feelings. Holding in old anger is caustic and unhealthful.

It’s also a waste of time and energy to blame that person for family dramas and your own upset. Blaming is a projection of our ego, where we don’t own our own shadows and ego issues, and we put them in the basket labeled: “It’s their fault.” And while it may be true that that person is the instigator of traumas, blaming him or her doesn’t help the situation and doesn’t balance the karma between you.

Breaking the Karmic Cycle

The first step to break this karmic cycle is for you to take responsibility for its presence in your life. Your soul agreed to be with this person because it was necessary for your spiritual progress. So forgiving yourself is the ultimate secret to healing everything in all directions of time.

This involves forgiving yourself for entering this relationship whenever you did in the distant past lifetime. You probably were given red-flag warnings by your angels then, which you chose to ignore or override. Forgive yourself for ignoring those red flags, and vow to listen from now on. Life lessons only count if we learn from them.

You get infuriated by how this person behaves. But this is how this individual’s personality works and has always worked. You were the one who chose to try to be in a relationship with him or her long, long ago. You were the one who decided that all of those red flags that your angels sent you didn’t matter. You were the one who decided that you could change or fix the person.

Now it’s time to let go of that fantasy that this person could be as you desire or dream him or her to be. You’re not the other person’s Source, nor are you the author of his or her life scripts.

Karmic relationships are akin to having a tug-of-war. They’re power plays, where one person will pull and the other person will pull back. No one wins in karmic power plays. But when one person drops his or her side of the rope (through the process of forgiving him- or herself for getting into this tug-of-war in the first place), the power struggle stops.

Use prayers for forgiveness for other and self.
Saying bless you to the soul.
Find reasons to be grateful.
Learn the lessons by asking them to be revealed.
