Does anyone here have psychic/PSI-abilites?

My take on this is that it is absolutely impossible to really understand higher concepts while incarnated in 3D.

I would add to this that because "this is not the density of wisdom," much more can be learned through the heart than through the head. 
As one is able to merge with a kind of innate crystalline knowing in the heart and vibrate with various energies of love, while one gains little in terms of factual knowledge, one's general vibratory signature seems to become notably less distorted, that is, more pure and supple.
I'm saying here that, on the one hand, acquiring greater knowledge and magical skill can lead to higher states of awareness, within 3D these are rather limited compared to the benefits arrived at using the route mentioned above.  (I'm not suggesting the two are inherently separate--of course, they are complimentary.  I'm just pointing out, as Willy Sutton would say, "where the money is.")  It's that fabled journey of 14" or so from the head to the heart.
