Outer Awareness is just that, awareness of things outside of you. This is something many people jump the gun on and just don't even practice in the first place and expect to be able to scan 10/10 with no problem and see in projection with no problem. It REALLY helps with all things senses.
Now then, the goal of this is to be able to feel your surroundings to a good degree, no, not to be able to say pinpoint a object nearby you, albeit, it can get to that point, rather, you'll have impressions of your surroundings, be able to feel movements of things in a way when actively doing it... Energy movements will also be feelable around you via this pretty easily. The physical effects are neat as well. Ever wanted eyes in the back of your head? You'll technically get such via practicing this.
Now then, let's get going on...For now I want you to get into a basic meditative trance similar to what we have already done. The only difference here is don't focus on separating the non metaphysical and physical sensations you feel, rather, close your eyes, preferably muffle your senses as much as possible. Next. I want you to begin to notice the air, what does it feel like? Temperature, cold, hot, what? Now, what of any vibrations you feel from around you? Something moving around? Keep doing this, this'll work on more of a physical approach, next off... I want you to concentrate some energy around you like your aura.
Then, send a small burst outwards all around you almost like a expanding dome, not too much, just a bit. This isn't the technique itself, but it'll help, as in, you don't need to do this as you'll become aware of around yourself without such awhile. But this helps, as soon as you do such, just pay attention, did you feel as if the energy suddenly hit something? If so, you likely just felt it hitting a object.
Now then, once you practice all that for awhile, we'll get to the actually technique... You gotta understand that there is ambient energy all around you, as in, non living. It is in every nonliving object, what you want to do, is to focus on it, become aware of it, got that?
Focus on it and connect to it, once you do such, you'll notice something interesting happening, many don't realize this, but if you do connect to it, you can get a general idea of the general surroundings of yourself. Of course, this takes a very long time to get accurately, but it'll 100% help you.
