'To see you must look without seeing'
I refer to UFO & 'Artifact' technology which regularly fills the skies of this orb. gazing into a clear blue skies with 'normal day eyes' will rarely herald a result, because most of the technology resides on frequencies which are beyond the mundane five senses world us material plane beings reside in.
I'm sure it is a deliberate ploy by the 'genuine alien' to avoid detection and to be able to go about their 'daily business' for reasons unbeknown to us limited sensory beings.
But, if you gaze at the sky without actually being aware of gazing; a technique I always associate with the 'sixth perception'; an ability to switch of awareness of the mundane five mortal senses and activate the 'extra senses'; then, the 'fun' begins and the phenomena can truly be appreciated.
You will find the sky literally filled with flashing lights, travelling orbs, streamers of light; ET & Artifact technology.
Initially, the logical brain will dismiss all the activity as 'the mind playing tricks' or 'electrical impulses behind the eyes' ... but if you can dismiss this distraction and persist in sky gazing ... you will commence seeing this phenomena with 'normal day eyes'. Effectively you will have reprogrammed your DNA/RNA/consciousness to perceive this phenomena which is just outside the normal perception levels. You will have expanded your consciousness and lifted your awareness higher than it was.
A 'downside' of this process is a new reality awareness where you will perceive the moving shadows and balls of light in the rooms of your home ... entities and beings that occupy that space on a slightly higher frequency to your own.
