It’s harder to relate to another person when you are generating your own negativity. All you can really do is be with that content. Witness it nonjudgmentally to the degree you can. If you can’t, notice that and forget about how long it might take. If your practice is good, it may not take that long. Developing that witnessing ability is like building a muscle. It takes practice. What arises may be unpleasant; it may not be. You’re learning to just allow it. Allowing does not mean being passive; it means being awake and calmly active. Eventually the ego lets go.
