You cannot free something directly.
A tight neck or back or arm is symptomatic of specific attention/awareness and a disruption in the unified field.
We may not realise that this has happened – it is a habit that becomes habitual.
It may only show up when, after decades of poor use, pain is produced. Once pain is present this exacerbates the problem as even more attention gets channelled in it’s direction.
The way out is in the exact opposite direction.
By becoming aware of the unified field these specific habits become clear – as we learn to trust the totality we can let go of the specifics and they fall back into the total pattern – neither more or less important than anything else – all seen in context within the whole.
With our awareness on the totality the unified field is seen to move constantly in freedom.
