Here I come with my hippy answer
I recently bought the book "The Intuitive Body, Discovering the wisdom of conscious embodiment and Aikido" by Wendy Palmer. In it she talks a lot about a "basic practice", which is a kind of meditation that can be very quick, or it can be drawn out over longer periods of time...the idea of it being a re-centring exercise to fill in all the little gaps in a day.
Basically it consists of: (this is a sitting medi)
Focussing on the breath, just listening to it, until it sounds even and calm.
From here, look to your energy field, is it even to the front and to the back?
To the Left and to the Right?
Above and Below?
How does Gravity feel?
There are several ways to expand upon this basic exercise, but I have been using it daily and it very centring for me. As far as I understand, it is working on creating and maintaining an open and receptive mind state too.
That being said, I am totally new to Aikido.
