The key way the teaching works is upon the mind by removing the belief in the notion of doership. This belief is the key source of suffering, and when this belief is seen through then the suffering which is dependent on it dissolves away.
Often there is a process by which the habitual tendencies that cause suffering gradually fall away over time as the understanding of ‘no-doer’ infiltrates and has its effect on the mind’s conditioning.
Note that the notion of a doer is a false belief – there is no evidence for a doer being present, just as there is no evidence for a volcano god that erupts volcanos or a sea god that ravages the seas. The lack of belief in a doer does not mean there is no action, just as lack of belief in the above mentioned gods does not render the volcano or seas impotent.
Action and movement continues as they have always done. They happen seemingly by themselves, spontaneously you could say. Live goes on, and it feels much the same, the whole range of feelings and emotions continue, just without the suffering.
