For us to respond to someone else’s emotion, we’ve to first allow ourselves to feel their emotion fully. We’ve to first let their emotion in. We’ve to allow it to reach our centres for feelings. For some of us, that means unblocking the passage to these centres. It means allowing entry into them to our own emotions. It means feeling the weight of some emotions, and associated thoughts, we’ve been holding back with effort. It means risking our peace and sanity. And that scares us.
