Please give us Feedback, Like or Subscribe, and if popular enough we will make more ! Tai Chi is a hard art to teach by video alone, but at least it allows you to get into a daily practice. If demand is there we will happily put in the time to add more specific videos, breaking down certain aspects we've not been able to sufficiently deal with in this video, like: feet, hands, breathing, theory...
So do please keep checking for further episodes on this channel.

Try to learn the form first, to be able to then concentrate on the internal, more meditative work. There is a lot to learn and practice, but as long as you get into a regular practice, you will pick it up soon enough! Energy/Qi will then circulate in your body from all 4 directions and you will find inner peace and harmony.
