The Mall Walk is blessed with multiple TaiChi teachers and some exceptionally helpful practitioners as well.
And yet, we are all at different places in our learning, have different bodies and experiences, and unique ways of learning.
I personally benefit from many teachers and many sources. Often a lesson from one instructor that confuses me suddenly becomes clear when I see the same thing from a different approach.
I encourage everyone interested in learning and improving their own practice, to look around the internet until you find what works for you.
