Amma the Divine Mother, the feminine aspect of God tells us that the DNA, chakras and aura are connected. Each double DNA strand produces a set of chakras. Each chakra produces a layer of the aura. With 7 primary chakra, you have 7 primary layers of the aura.
Now that 10 additional strands of DNA are unfolding, what is called the Crystalline DNA, you have 5 additional sets of chakras formed. Each of those chakras produces a layer to the aura.
These energy structures are super imposed upon the other. You have 12 strands of DNA each producing a set of chakras and layers to the aura which are "layered" together. There are 6 "First" Chakras and 6 of each of the other chakras.
The same is true of the layers of the aura. Each of the aura layers are gathered together. (Six first layers, six second layers and so on.)
