Well erm... a polarizing topic to discuss for sure.
Did you really want to discus it earthair, or where you more up for enrolling us into your idea that it can't really be done as you believe? (Regardless of who's said and written what, their viability as instructors, and whether we could have time machines. And - this question is rhetorical.).
Next magickal topic please!
(that's the best thing to do when we can't agree ).
<nods> sometimes 'secrecy' is invoked by the listener.
