Find ways in the principles of ahimsa (non-violence) to let the person know why you feel uncomfortable around them.
Also ask yourself, “Is it them? Or is it me?”
Often times when we have such adverse feelings towards someone it is because they are mirroring something that exists within us which we don’t want to look at.
Perhaps they shine light into darker places within us, making us feel extremely uncomfortable and hence we create negative thought patterns towards them and throw energetic low vibrational arrows towards them, hoping we feel better ourselves.
The reality is this tactic never works.
Another possibility is fear. This person may be showing you something that is unfamiliar to you which causes you fear, in which case is also about you.
If you catch yourself doing this, take some time and go inside. Sit and meditate or go on a mindful walk (no electronics here—just you and the trees) and try to work this through your own system.
Allow this vibration to continue to make its way out of you.
See how you feel after and if the feeling is still there, communicate with that person—and you most likely will work things out.
If you don’t, maybe it is a good time to suggest some time apart from this individual or individuals so things can get to a neutral place, a place of more equanimity and less destructive thought patterns.
This is if you care about the person or situation, because if you don’t care, you can simply walk away.
Walking away is not always easy, especially if is a family member. We all know that. Relationships between parents, sons, daughters, or siblings can be complicated. Adding their significant others can get even more complicated. But as I said, thoughts are things. If you choose to preserve these relationships, it is important you communicate the bad feelings, or the results, can be complete separation from those you love.
Many spiritual teachings talk about close relationships being assignments, whether family or lovers, they represent maximum growth opportunities—so we can face our fears and learn how to love deeper.
