The three lower chakras are the root, the sacral, and the solar plexus and the three corresponding subtle bodies are the etheric, the emotional, and the mental body. They are very closely intertwined with the physical experience more so than your higher chakras and your outer subtle bodies. The root chakra and the etheric body are closely intertwined. The etheric body carries the blueprint of your physical form. It’s like a mirror of your physical form. It is through the root chakra that one finds that security and safety in the physical realm. The next chakra, the sacral chakra, is connected very closely with the emotional body, which is the next layer in your auric field of the subtle bodies. It is through the emotional body that one receives messages from the soul through emotions, feelings, states of being. The next body and chakra is the mental body and the solar plexus chakra. The solar plexus chakra is the seat of you feeling your own power as a unique being walking the planet. A unique expression of the divine. The mental body is associated with the solar plexus, where all your thoughts reside.
