Tai Chi is hard work.
Daily practise with purposeful intent is needed to understand and progress, whether doing the solo forms or working with a partner.
The following quote from John Kells sums up the deeper meaning:
" Throught dint of hard work all is revealed
When all is revealed then all is concealed
When all is concealed then principle is revealed
When principle is revealed then inclusion is revealed
When inclusion is revealed then nothing is revealed "
