The etheric level carries sound. When we fall still and listen we connect with the etheric level. We experience it as a vast space. Into this space comes peace, answers, and a feeling of connection with whatever is “on the other side”. One of my students described the etheric level as a portal (he’s a great Stargate fan), he recognised it as way of transporting oneself from this world to another.
Everything in our physical world is created from the causal world. It Is quite literally the cause behind all things, whether they be animate or inanimate. Yet nothing can be created unless it crosses through the etheric level, this magical bridge between one world and the other.
