I.  Front Brain -- Registration Area

I -- Intellectual  E -- Emotional  S -- Sex  M -- Movement  Centres No modifications can take place as manas does not meet memory patterns and incoming impulses do not flow in the central passage over the top of the brain. Essence of consciousness now has a link with Consciousness through bindu. (7) , A -- Ajna (magnetic point) : Sattvic energy flows out from here --in intuition, there are minimal modifications of mind and no excretions from base thought forms. This stage is non-sensory -- to be in this stage for even a short time is to be unaware of space and time.

II.  Mid Brain

(P1) -- physical  (A2) -- astral  (M3) -- mental  seed atoms

Now, along with (P1), the astral seed atom (A2) also starts pulsating and transmitting the activities and steps the individual takes in the physical life and in the emotional/astral realms for the corresponding  permanent seed atoms in the causal body to register and record as permanent memory.

(9) , B -- Bindu  (8) , S -- Sahasrara (the corresponding area in the physical body is the thalamus).

IIIa.  Memory pool shallow : for memory accumulated in the present life.

IIIb.  Memory pool deep : for memory brought over from previous lives.

Both memory pools are effectively bypassed; consequently sattvic manas and the thinking instrument are not made use of. (0) , T -- Taluka : the block $\otimes$ here is consciously closed to manas, i.e. incoming impulses, which in relation to the astral body are various grades of prana.

IV.  Force Centres along the Spinal Column :

(6) , V -- Vishuddhi  (5) , A -- Anahata

(4) , M -- Manipura  (3) , K -- Kundali

The block O at the lower end of sushumna is open to allow the flow of manas in the central spinal passage in the astral body. The block $\otimes$ at taluka is closed to the normal flow of incoming impulses --it prevents manas from flowing over memory patterns through the central passage on top of the brain as in the diagrams of stages 1, 2 and 3a. There are no incoming impulses entering the brain region either, however sattvic they may be. Mind modifications have ceased! Sattvic manas has direct entry into the registration areas via side passages, and thence onto ajna, where it flows out in combination with influences emanating from the centres 9-->8-->7. This is the early stage of pratyahara, or intuitional stage of the mind.
