Peace on earth, starts with peace in the home and within ourselves.
Quiet time and grounding oneself through, meditation, calming music, reading, prayer, whatever works. Unplug all the tech toys and write, draw, colour, play a boardgames/instrument.
It is simplicity that will resolve the complexity.
Maybe even have a conversation. It doesn't matter who is right, only what is right for the peace and in our world, that means communicating in a a positive constructive way, taking time to not just listen, but to really understand.
Budo is a path to peace and the way is in the training. Have a cup of whatever your 'Zen-green tea-eggnog' is this year and remember,
To reach enlightenment,
you only need to enlighten up a little.
