with clairvoyance you see things but not necessariyl understand what is being seen.
Also, what you see can be distorted by your own personality, and because of the lack of understanding mentionned above, you dno't even know how and how much you distort your own clairvoyant perceptions.
Forget about developping claivoyance.
It's safer and much more worthy to understand the spiritual workings FIRST, then to compare what you see with want you have already understood.
Then you can clean out your perceptions from all subjective bias and distortion.
People fall prey to the eight sphere when they start seeing clairvoyantly into the other worlds nearby our normal sphere of experience. This is because the etheric body is growing lager and extends now beyond our physical body, a few inch out of our skin. It is also growing loose, and we have less and less control over it, in fact we fall all the much easier into fantasy and hallucination when we have clairvoyant skills, and vanity and self-delusional thinking.
Straighten out your thinking then look at yourself objectively, coldly, as if in a mirror. Are you anxious? This is an exemple how crossing the threshold is disturbing: the (ahrimanic reptilian) Double is there. we are more illegible to getting locked and entangled into his intrigues now because we are all the more on the borderline of the threshold, as a global human race, as we have never been before (except in the beginning of kali yuga, about 3000 B.C., when the etheric body was gettnig more locked into the limits of the physical body and head, now we pass again throgh this stage but in a reverse way.).
Evil today have more links with this crossing of the threhsold. We al see that we hold in ourselves the potential of great evil, but also the intuition for greater good - yet we lack the will power to act according to those karmic intuitions. Listen to them. Listen to the karmic balance inspirations and follow those karmic imaginations that come up in such times when you "see through" things.
