In this case, I am sharing the practices standing up, as it is often easier for people to learn them in this form, but also they tend to produce a natural qi gong like response from the body as you allow the waves of energy coming up to move you until the ripples settle.
When you do this in Seiza, Japanese kneeling, it often produces stronger reactions which I don't necessarily want for my students at the beginning.
Kishi Sensei never taught this standing up in my experience.
The core of this work is still the breath, so it is worth practicing with the Sitting Yawning Yoga practices before approaching this video. The opening exercises magnify the hara opening, bringing up stronger responses.
As with the Sitting Yawning Yoga, after each 'hara stimulation', dropping a pebble into your pond, you allow the body's natural responses to come up, yawns, stretches, shaking, burps, coughs, emotional releases.
And then when all is quiet you can drop another pebble to release more deeply.
The most important thing in this practice is to relax about what comes up response wise. If you are afraid and tighten up or hold it back, it creates an unpleasant tension and leaves you stagnated which isn't healthy. Its a bit like holding back a sneeze.
I noticed with a few students who were quite head based, possibly psychologist trained, that they went into a fear state doing this work which produces an uncomfortable result. There is no need for this, but if you are not ready to surrender the ego's control and let go, you may not be ready to do this practice. It requires a leap of faith like jumping off a bridge and trusting your bungie rope will hold. I was afraid the first time, but was even more afraid of staying the way I was...
When I hear about people with aggressive voices inside, I want to offer this work, as I'm sure it will discharge the emotion from the system and ease the inner relationships but what is likely to come out will not be 'tidy' to use my language and facilitators need to be prepared for this. I lost my voice after two of my early retreats working with Katsugen.
A safety note - For some people and I was one of them, there can be so much energy stuck inside needing to get out, that it can come as a real volcano of 'demonic rage'. Harmless in my case, but impressive and scary for myself and those around. This is amazing to go through if you have been holding it in for decades like I did, but you need good support around you to keep it safe.
My view is that if you have a lot going on inside, you should work with the sitting yawning yoga practice for longer, quietly titrating the emotion before approaching these practices that take you deeper.
Ideally when you do go ahead, you will do it in a group, with experienced people present for the first few times.
Thank you for your wisdom in taking care of yourselves!
As with any practice I share, anyone following this, does so with their own responsibility for themselves.
This is a healthy natural process, but for some people anything that brings you to a state of relaxation and connection to oneself will bring up emotions which you then have to face.
If there is a need to talk to a therapist though about what may come up, please do so.
