As we look at nature we see that nature easily balances herself, but as soon as humans entered the picture and put profit and control above all else, in that moment, we became massively imbalanced. In order for us to balance our outside world we must balance our inner world. But in order for us to take that step honestly, we have to accept that our inner world creates our outer world. It may take some time for people to make that connection, but when they do, then they can take that next step with more faith, thus more manifesting power.
So if we are manifesting things in our life that makes us uncomfortable, we need to heal the inner world for that to manifest differently. That is how the connection works. If you think that changing your outside world will make a difference in your inner world, you will shortly (hopefully) realize that it's the opposite that is true.
When we balance ourselves, we then have an overflow of love and understanding for the world around us, and thus the domino effect of healing energy takes place, cascasding beautifully. So this inner balancing not only physically heals our body, but also our minds mentally, and thus our emotions, which is then energetically felt by those around us, whether conscious or not.
