Ajna (Kutastha or the Void) is not in the mind, even physically speaking. Its where the nervous system meets the void in the center of the brain, or where the cerebral spinal fluid is (ambrosia.)
I have been 100% withdrawn into Ajna and before I go, I take or release a breath. Time passes. In the beginning I didn't remember anything. But I completed my breath, opened my eyes and hours had passed. It was past midnight. I looked at the clock, unable to comprehend what happened.
I hadn't even moved an iota. This persisted, until then I could remember what happened. I was in a state of supreme bliss.
One day, I overshot Ajna and ended up in the 7th chakra area. As I did so, I could see through my head in the surrounding room. There were astral beings standing around me. They were there the whole time. This is true astral projection.
I then realized that Ajna is the fulcrum of balance point where we must go in order to reach Samadhi. One must cut the knots that keep the energy in the body, in order to get there. But one must not overshoot, as do all people during death, otherwise you just end up in a different Matrix far more difficult to overcome than this one.
From Ajna there are two places to "go" which are close by, the first is the Void itself or the third ventricle. The second is Kutastha, which is towards the point between the eyebrows. Both are states of being without body and mind. Kutastha is the "final" form of creation. Beyond Kutastha there is no form nor duality.
Once you have a memory of Samadhi (the second stage of Samadhi) everything is clear and you can read a religious book or hear a lecture and know with authority whether this "guru" is full of it or not. You can tell whether he comes from the point of view of the mind or of Samadhi. If he does not speak of the knots (or seals) and Ajna and Samadhi, then he is just an agent of the Matrix, another level of control.
