Tai chi chuan form is often portrayed as being easy to learn. This is a common misconception.
It is important not to think of tai chi chuan form in terms of external kata.
Kata and form are ultimately not the same thing.
Form teaches 'a way of moving'. A style of using your body. A habit.
A kata is considered 'correct' if it looks accurate and crisp.
This is not the case with a tai chi chuan form.
A form must be performed in a relaxed manner, with attention to how the power is being generated.
Every movement must contain peng, and would be completely useless without it.
A comprehensive understanding of how to apply every nuance of form is necessary for true understanding.
