I am a person who has been attacked and also protected others whilst they were being attacked but I have to agree that we have to practice with love in our hearts and not only in the dojo.
I was was taught that a real master is someone who takes the negative in the universe and makes it positive. Loving protection can save your life. It is a much more realistic approach that anger, vengence, hatred, which is where the attacker is coming from.
I donīt live in a violent society, my ideals probably reflect that. If I lived in a place where I felt my life was under threat walking home at night, then maybe things would be different but isnīt aikido the Way of Harmony? or, The Way of Peace?
Love and Light
