Well he's not referred to as a "Master" .but when you see the way he is addressing folks and doing his caligraphy, I get the impression that he is thought of in that way.....it's actually a very hard subject to discuss because we all bring our life experiences to the table and mine can be very different from say yours, which all adds to the difficulty of the discussion
For myself I have seen many folks who at first appear humble and spiritual but when you dig a little you find that they are probably less humble and spiritual than your average Joe

........they invest a lot in their own little subtefuge and others who wish to find a "Master"back them up on it....I have known quite a few people in Aikido and Tai-Chi like that.....and it is very common in "Spiritual" circles...so you can see that I am a little sceptical.I mean why is he doing his caligraphy while he is talking to folks? .........isn't that a little rude
I'll share some stories here that might amuse
I once studied Tai-Chi under the daughter of a very respected master.when we broke for lunch she got in the lotus position and started to meditate...while we all ate our sandwiches and drank our tea.....later on she gave a demonstration of a Shaolin form, but half way through it she had to stop because she ran out of breath
another Tai chi tale
I used to train with a bloke who could really do the most excellent form.........it was a fairly rare style of Tai Chi called Hao style......every movement he did was perfect and precise and he won a major martial arts competition by doing his form................However, he was going through a really messy divorce at the time, and he was smoking and drinking too much and generally being a real arse to people............but when you saw his form you just thought WOW....and in my mind at least I tend to relate a good tai chi form to some sort of spiritual development, peace of mind etc...............When I know that I shouldn't

.....a form is just a sequence of movements, the external does not mirror the internal in my experience........so coming back to our friend Kaz...he may just be a very rude man doing doodles and bullschtting other folks ( and maybe even himself) into thinking he is something more. As they say " Humility is just a debased form of inferiority complex"

.........but then again maybe not
