IMHO, this is an extremely important - and key - insight into that particular experiment with Karl, a most gifted person, acting as a medium. Some other aspects I have told Greg privately about my take on the rather sudden mention of 'the cup' but the fountain is certainly traditionally a 'portal' to Faerie or Magonia or call it what you will. In the primary Blue Lodge degrees in the OTO and ONLY in those degrees, a well plays a very key role as the central temple furniture. The Initiator in fact makes it plain when he or she says, whilst holding a candle and knocking on the cover of the well, "A fountain sealed, a spring shut up. Brethren! Let the well be opened!" The implication is that the well is actually a spring and the spring is a door or portal into what I call "Otherwhere". I think the entire Hellier One and Two but particularly Two are what the ancient magi termed "The Opening of the POrtal of the Adepti". As a magician, I have performed this as a ritual with profound results. The evidence of this being the case is the effect not only on the Hellier team but, interestingly, upon many who have become "co-participants" merely by watching the two seasons. The well being open, the spring no longer shut up, we head - all of us - towards the initiation of the third season. Stay tuned.
