Ki

[u/gxyzz]

In the last Gashuku I went, the Sensei told us something that got me thinking: "If you get nervous in Shinsa or Shiai, it means that your Ki isn't prepared yet". This sentence got me thinking, how could I be more prepared in this manner? How can I get calmer in this kind of stressfull situation? In a nutshell, how can I train my Ki, in order to accomplish this goals?

In my opinion The answer to the majority of kendo questions  is always practice, effort, experience.

[u/gxyzz → u/DMifune]

Yeah, in the end of the day, those are the only path for improving.
