Why do we sometimes feel lighter? For instance, if something desirable happens, or we have a release through inquiry, Vortex Healing, TRE, or something else?
Stressful beliefs (identifications, trauma) come with muscle contractions. In order to believe a thought, the thought has to be associated with sensations, and these sensations give the thought a sense of substance and reality. The thought feels true. The easiest way to have these sensations readily available is through muscle contractions. So when the mind needs to believe a thought, it contracts associated muscles to provide sensations, and these in turn give the thoughts a sense of solidity and reality. These muscle contractions feel dense and heavy. We – almost literally – feel the weight of our stressful beliefs or identifications.
So when we are either distracted from these stressful beliefs, or they are released, there is a sense of lightness. The muscle contractions lighten up or go away, so we feel lighter.
