We can start doing more of sanchin practice any time we want ,again to highlight a theme of my posts there are difficulties one would encounter en route such as trying to get into action ,then keeping the momentum going .
Going back in time when every uechi practioner had to spend the alloted timespan to sanchin ,I think this has mostly been swept under the carpet ,and when some one actually knows the ins and outs of a serious encounter with nothing but sanchin for long duration ,all sorts of emotions and deniels can surface .
When i first wanted to undertake a long term sanchin , I was met with a very difficult time of people getting their heads around the idea . and impossible to deal with negativity ,fortunatly a few wished me well .
If the Ryu is catering for this, its no big deal yet because we have to go back beyond fifty or so years ago ,most have forgot about it, its a memory .
If all I do is sanchin ,how am I going to defend myself ?,remember nowadays in uechi ,most have a moderate arsenal to weave and mesh with vary degrees of knowledge to their sanchin ie; more scope ,yet with a total devotion to nothing but sanchin ,can't sanchin deal with say what seisan is supposed to do .
To go farther there is a must to study sanchin considerably harder .
