There are considered to be seven layers of auras which get progressively less dense as they emanate away from the physical body. These seven layers are often associated with the seven main chakras.

1. The Etheric Body is considered to be physical blueprint of the body. Like the base/root chakra, it relates to the health, survival and security of the physical body. Physical signs of illness and injury can be seen in this layer. The etheric layer is closest to the body and fits nearly like a second skin.
2. The Emotional Body relates to emotions and boundaries, emotions with us and emotions we have for others around us. The emotional layer is often seen as a swirling mass of energy around the body. The form resembles the human shape but is not as defined as the etheric layer.
3. The Mental Body relates to basic beliefs, intellect,  personal power and understanding. This is the layer of thought and ideas and is often seen around the head and shoulders as a yellow glow. It is in this layer that thought and ideas actually become substantiated.
4. The Astral Layer is the division between the physical layers and the higher layers. This layer is responsible for interaction between people. It is the layer of love and relationships, corresponding to the heart chakra.
5. The Etheric Layer becomes more abstract. It is a copy of the physical body on a higher level. It is the basic template of ones uniqueness and inner identity.
6. The Celestial Body represents the emotional level on a spiritual plane. It is related to group consciousness, clairvoyance, and unconditional love.
7. The Ketheric Layer or Causal Body is sometimes referred to as "The Divine".. This is the mental layer on the spiritual level, it is our spiritual template. Through this layer we meld and become one with Spirit.
