SPIRIT = Breath

Working on your spirit is not building courage that can wear out or “learning ” to withstand pain but gaining awareness through the fog of tension and perception of what we can truly do.
Start by doing simple tasks like drawing shapes and walking in a straight line while slowly inhaling or exhaling till there is nothing left and then add a bit more on what you perceive as empty.
Swim underwater while slowly exhaling of if you have a tube inhaling or close your eyes and look for a pebble at the bottom of the pool while you exhale or run on your last breath. (important to have a buddy who does not fancy your woman to guard your back if you lose your consciousness here)
Proceed from simple tasks that do not require more than a “stored procedure” of motion to tasks that are more whole in nature so all the dust can be removed from both intellect emotion and body noise.
Add the drill where people walk through you and you evade them while exhaling or inhaling to the end and see how this fares in comparison to the previous jobs. Give them wood meat sticks like the ones used in kebabs and have them repeat the drill with the pointy end toward your stomach and later on add a rope they can hold between them to create a wider obstacle to make use of.
Another example to a more complete task is to keep contact with a partner holding a blade in one hand who is working to remove your contact from him using the blade. You place your hand on the back of his neck, he moves the flat of his knife on his neck and you remove that arm and place the other on his stomach without losing contact with him and so on.
Yet another example for this level of drill is to close your eyes and go from one end of your house to another on one exhale of inhale of without any air at all. Later on adding no contact or noise to the drill is very helpful for soldiers and civilians alike. The same works for any piece of bush with no mines in it.
Now we proceed to a more open drill where the objective is not defined in advance in some ways just like life and in particular the myriad of conflicts we are a part of during ours.
Start with the obvious of having a bunch of people walk past you with different intents from dragging you to their trunk (not an elephant man joke) to asking for the time to picking your backpack and so on as you breath calmly as possible and learn you do not need to tense up or hold your breath toward impact or contact and not everything in life is black or white.
Continue to restricting your breath to uneven breathing (One pulse inhale and three pulses for exhale for example or One for inhale and ten for exhale and so on) and repeating the drill as listed before.
Continue to a more focused but shorter drill of doing this during one prolonged inhale or exhale or one of them and a breath hold to the end at the end of the extended breath while you repeat the drill with the several people with several intents.
Continue to the best drill for this of one group on one group play without telling the other team what you set up to do but have one person know all intentions so there will be no unhappy accidents like impalement and injury…
Have some fun and learn something while you do it .
