I’m not an instructor or an expert, but here’s my angle:
Firstly, recognising that there is an internal ‘switch’ is a good start, you just have to find out how best to turn it on an off and decide exactly the mentality you’re trying to cultivate.
What you train for, you will get. So if you want to be able to produce that ‘forward drive’ in real life, that’s what you need to be doing in practice. Each time you work on it in training is a chance to ‘switch on’, power through the threat and then bring back your rational thought processes at the end – that’s when you will be needing to assess a real situation, maybe call for help or find the exit in a real scenario.
It’s a good idea to think through your world view, Buddhist or otherwise, and how it relates to your RBSD training. Do it in a quiet moment or over a period of time but get it straight so that you’re not trying to make decisions under the stress of violence. For me, it’s about recognising that I am protecting myself and loved ones. I know that if I ever have to use the stuff I’m learning (and I never have so far except the awareness and avoidance) then I will need to give it 100%. I’ve been guided through visualisation exercises to experience and harness the kind of fury I would feel if someone harmed a person I care about, which was helpful.
‘Anger’ is not the quality I’d be cultivating. I usually like being softly spoken and keeping a low profile. When I ‘switch on’ I want to have the fearsome forward drive and combative mindset that I associate with the best RBSD instructors and soldiers in the world. It’s extremely powerful, but as soon as the threat is taken out, it switches back to a rational and professional attitude to face the next challenge.
