I'd say that this word "illusion" is one of the most important ever posted on this forum. Pre-gyan, many of did not like the illusion of our lives and therefore searched for reality (mixing up reality and truth in the process) and found it for a blissful period of time within the separative teachings of the BKWSU. Then it took a while to admit to oneself that Gyan, as taught in their centres, was also illusionary in nature and eventually we rebelled and left. Some later rather than sooner.
It goes to show that at heart, we are an inclusive-intelligent being and one that is constantly attempting to separate reality (that which is real as in, "hey - get real, dude") from that which we assume to be illusion.
Should not our search be to identify that which is illusionary in our life instead or is that itself an aspect of separatedness? Then no one could fool anyone into believing something that in itself requires us to separate ourself from the rest of society and the world. And we may then begin to understand some of the reasons why the BKWSU continue to perpetuate the illusion which they teach and practice will create another reality on earth.
