Square form

A beginner must pay strict attention to the lessons taught in the body qigong/neigong exercises.
The alignment concerns should be directly employed in the form.

When a beginner can perform the sequence accurately (albeit robotically), they have the 'square form'.

Tai chi should be "Square on the inside and round on the outside".
This means that the internal framework and network of body parts must be aligned and moving in linear paths of force.
If you skip this stage of your training, your form will be devoid of power.
