Eventually I found the Connection Practice, which combines the empathy I discovered in Nonviolent Communication with insight through heart-brain coherence. When I was learning Part 2 of the Connection Practice, I used the case of my son not being able to walk and I guessed that my son was feeling lonely. The insight I got was an image of a walking trail in our neighborhood. I realized it had been a long time since I walked with Makoto and I could invite him to go for a walk.
At breakfast the next day, I asked Makoto, "Would you like to go for a walk with me on the next holiday?" He said, "Yes" with a radiant smile I had never seen before.
Then I asked, "I'm wondering, is it important to you to be connected heart-to-heart with me?" He thought for a while and then said, "YES", again with a smile I had never seen before.
I had never noticed Makoto's facial expression before and was only aware of it now because of the empathy and insight I'd learned from the Connection Practice.
That evening, after nearly two years, my son started walking again. When I heard that news, I fell to my knees in gratitude. My son had never told me he was lonely, but his body was communicating that by not walking. Now Makoto is healthy and he participated in the first Connection Practice Family Camp in 2016.
Since then, I spend as much time as possible with my family and I listen to them empathically. I'm happy just knowing my family is in good health.
