For me, the teachings of Adyashanti - and all other non-dualistic teachings - are like reminders of that which is on the other side of the barrier (which is also on this side of the barrier, but this only dawns on us after the veil separating the two had been cut through).
There is a hidden being in me - a mirror image, living on the other side even in this moment -, that can appreciate these teachings. Through the understanding of this hidden being, I sense how they are right and that's why I dare to post them here. The same with Chögyam Trungpa, or everything, really. In spiritual matters I follow the inspiration of this hidden being, let's say my instincts, because in these lands there is no other ground.
I cannot give practical advice on how to complete the circle. Here is what I do: I am churning this dualistic reality, by which I slowly gather all the bits and pieces of the puzzle (my mind) into one large pile. My everyday life is this churning, meditation and other so called "spiritual practices" may only speed up the process. The desire to become enlightened is a special one, because when I totally give myself to it, everything else will be consumed by it. Other, worldly desires are not such: they only cover parts of my existence, therefore the pile they create is also partial.
I think that when my pile is ready, someone will come from the other side and ignite a cosmic fire. The pile will become a sacrifice, my ego offered to and burnt into nothingness by God. That will be the completion of the circle. The gathering of the pile is a preparation - this can be done (or assisted) by me. But the awakening - the overcoming of the dualistic barrier - is not and cannot be my part, I could not do it from inside the dualistic world.
