The people from ancient cultures knew and understood that beyond its physical form, the human body has a pulsating, dynamic field of energy called the Aura.
The Aura is an area of protection that we all possess and some people refer to it as their personal space or energy field.
This invisible bubble of energy that surrounds the physical body can change in size and colour depending on how we feel. When we talk about good or bad vibes we are picking up on the vibration of other energies.
When our personal space is invaded without invitation we feel uncomfortable and irritated and when anything comes too close for comfort we automatically pull back and our personal space shrinks. When we are feeling happy and relaxed our personal space expands.
