Hey Uggy,
I am exploring the connection between Shikantaza and anxiety, too.
I have the tendency to creating feedback loops, that grow with each iteration,
resulting in anxiety about having anxiety about anxiety until the whole thing explodes.
Some of the things, that go wrong in the world seem to be based on those loops.
People arguing, one word giving the other, getting louder and louder, starting to fight, until one doesn't stand up anymore.
That's not just individual people, countries are doing so, too, engaging in war and violence.
Buying precious things that loose it's significance as soon as one possesses them and starts hunting for the next, even more precious thing.
Even machines know these kind of growing vibrations based on swinging up resonances, until they destroy themselves.
In all cases, the solution seems to be that one has to break the loop, knowing when it's enough.
One side has to stop reacting on what is happening.
Shikantaza, to me, is exactly that. Stop reacting. Acknowledging the thought. Watching, not engaging.
The initial thought - OK. Thinking about the thought - already one step too far.
I am sorry that I wasn't able to stop after 3 sentences.
Gassho,
Kotei sat/lah today.
