We have heard about aura around our body, also called the auric field. As we move outward from our physical body into the auric field. there are layers that vibrate slightly faster than the previous one.
These energy layers are called Subtle Bodies. We can not see them like cosmic rays or radio waves. These subtle bodies connect us to the energy of the universe. Each one of us has our own specific vibrations. that is why we radiate different energy.
As we continue our sincere practice of meditation our awareness of subtle body increases.
