i think I understand you mark... but wouldn't you also say that concentrating on getting results (proof) rather than just training and getting the technique right, can create tension if you dont get what you expect?... considering aikido takes so long to even begin to get a true feel for the basics...??
this is the point at which you have to have faith that you are progressing isn't it?, because more often than not, i dont think you see yourself advance even though you are... i think maybe, asking so many questions like you say can help... but then i think asking and searching frantically can also block you from what is already there, your just not realising your feeling it already... or have i got the wrong end of the stick here?
considering this `proof` that you know you have... surely you have to have faith that its still there?? - have faith that you know what you believe in is truly proof...?
