(Outside of a lesson) there is nothing better than this active-rest position to naturally rebalance you.
It is the habit of continually using the floor that is the key – continuity of practise is the secret of success.
It doesn’t matter if your mind wanders some – don’t be too strict with yourself to get back to the “directions” – let it build underneath any chatter – and in a natural way your attention will shift to a leg, an arm, a back and then to something else either a thought or something physical.
Consciousness IS movement. And we want to not put the brakes on it but slowly redirect it to be more constructive.
The floor will do this – with the aid of gravity and with the direction to reduce reduce any physical/mental effort – to let go completely but to still be completely alive and aware of the totality.
If you notice that you are thinking a lot of just other things in the mind then it is caught up and fixed and you need to re-anchor yourself in the body – so simply decide to make a choice to move a leg an arm using your directions with full awareness.
