"One"

heaven + earth + heart = one

speak | demonstrate | do when combined into "one" provide guidance in following the "Way" or in practicing the fighting arts.

Learning is a combination of Sensei or Sempai speaking to you or providing you details which must be followed up with a demonstration the Sensei/Sempai performs to relate visually what was perceived by hearing the spoken word.

You first hear what Sensei/Sempai is telling you (8) then when Sensei/Sempai show you then you shall see what it is they have told you (7) and finally Sensei/Sempai will want you to perform for them (do) so they may see what you do and then make appropriate corrections.

In life one must actively listen to what is said to them with an open mind, with out judgement, to receive the spoken word. In life one must couple the spoken word (hear everything; 8) with the persons attitude, demeanor, body language, environment, customs, and perceptions (see all; 7) so they may understand them totally (1) so that decisions can be made within the moment (to bring it all into "one").
