"Uncle Po, what is a flow?"
Old Po got a confused look on his face which he made sure to hide almost the instant it happened "A flow is the flow of energy throughout your body, for every person it is unique and travels more or less fluently as well as with more or less force and more or less rich with power, a flow can be harnessed to push the body past what can be reached through exercise and even make steel like hot butter under the sheer power of the hand closing. Though obviously it is a harsh and time consuming process so if you do not have a strong will and strong means to exercise your flow then it would be nearly impossible. There are many different mantras and ways of life, as well as evil paths which ruin the soul."
"How do I practice my flow?" Jin had become really invested and had decided that this must have to do with why he was put here on this world.
The old man had been wondering if the boy had lost all his memories when something happened in the forest, even when he asked the boys name it seems as if he made it up, when he went into the forest with the boy the Young Jin had asked about almost everything and seemed absolutely clueless. If there was anyone I could teach it to, it is this Young Jin. That was the thought going through Old Po's mind. "In almost every different family they have their own mantra and way of life, they bind this mantra to their souls and when following this to different extents their flows not only grow stronger but gain more potential, if someones mantra was to farm and they farm for 3 days they grow stronger, but they do not have to farm more to grow their strength. They can increase strength by cultivating but they can only cultivate so much if they have only farmed 3 days. My family has a mantra but if you would like to learn it I must warn you of something, my mantra will increase potential greatly the more you practice but the strength that increases is not as superior as others, and you must have a kind heart or it is useless to you. The mantra will also bind to your soul, you cannot learn another mantra nor can you switch. Give me the word and I can bind it to your soul." The old man felt it was needless to say the other detail as it probably would not do much.
Jin thought for a moment about whether he would want greater potential but less strength than othera provided, or the opposite, but decided to learn this mantra as probably nobody else would be kind enough to give their family mantra to a stranger. "I am ready."
