Re: to look at opponent's eyes or not?
Like you I have received this information of concentratng on looking in to the eyes of opponents etc.
Like you it just does not work.
However Osensei stated that we would lose our souls should we practice this way.( death??)
Certainly practicing with the major use of periphery vision does work. The use of the core of the eye produces tunnel vision and a lack of suble or direct response. I feel you have received some good answers to your question. Thank you.
