I agree. It can be used effectively in techniques or as a principle to overcome various peoples mood swings in your daily life. You touched upon something very important as neutrality, calmness and emptiness are true indicators as weather you can be non-aggressive.
But in order to obtain neutrality, one will have to be able to contain people and be non-judgemental of them. This is difficult but also the right way.
Glad you liked it. Liked the non judgemental observation and that it can serve as guide. From observations like that we can enrich our understanding in Aikido and see the type of mind we should face an opponent with.
