Freedom of or in movement is obviously an asset and of course a useful pursuit in the world of homo-sedens that abounds these days. However movement according to the principles inherent in Haṭha Yoga has a further role other than mere freedom of movement as an end in itself. Thus in Haṭha Yoga the role of freedom in movement, albeit embedded with useful anatomical insights, is not the priority that appears to dominate the forms of Āsana utilised within many popular Yoga classes.
Of course freedom in movement is obviously a support in allowing us to apply the principles of Haṭha Āsana practice, but it is not the end in itself it seems to have become under the guise of calling it all Yoga. For example it can help with facilitating an exploration of the energetic processes that ultimately define, guide and differentiate Haṭha Yoga from movement forms such as exercise, fitness, dance, etc.
Yet these days it increasingly seems to be that, on the journey towards the deeper purpose inherent in Haṭha Yoga and its relationship to Rāja Yoga, we are more and more being sidetracked by the goals within the myriad of movement forms that proliferate or even ‘pose’ as Āsana practice today.
