Voluntary Efforts and Involuntary Effects in an Āsana Practice

2. Thus, this means these effects can also apply to our
attitudes whilst working habitually in a particular Āsana.
For example, an involuntary response as a result of memory.
So we can have a blindness, in that we are unaware of the
position of the arms, legs, or body, as well as in our attitude.
Thus, we need to at least apply movements voluntarily
in our efforts to influence the qualities of the Āsana.
