You can’t see your nerves and nerve ending with your eyes, but when you feel: softness, roughness, textures, pressure, pain, you know it’s because of your nervous system. Other people, doctors and such, tell us this because they have seen it.
It’s the same with energy. We experience feelings, perceptions, intuitions, through our energetic system. (Most of us) can’t SEE our energetic system, but it’s still there…just like a nervous system or circulatory system.
What if doctors had no idea that we had a circulatory system? and you went into a hospital and said “Help, I’m bleeding!” they would have no idea how to help, what to do. They may even give into their ego and tell you the bleeding is all in your head. They’d say it must be psychological because they can’t see the blood vessels, the blood, the life giving substance.
Even if you can’t see your aura, your chakras, the energies people put out in a room, it is still just as ‘real’ as having the sense of touch, or smell. We perceive energy as our sixth sense. Your energy systems and intuition is just as real as the small of bread.
