I see the Seven of Discs as a card of difficult, back-breaking work. In the RWS it would appear to show Adam after being banished from Eden, toiling in order to make his daily bread. Mercury has little strength this far low on the Tree, and stands little chance of rousing placid Taurus, especially in the sphere of Venus.
Since the sixes show the element in its ideal form, the sevens show that which is missing in order to achieve Eden once again.
As for bonding, like Aeon I don't really go for it. It would be a great understatement to say I like it, but if I bonded with it, it was by learning about it.
If you don't mind my saying, it sounds like you're trying to superimpose your own ideas onto it, whether it be RWS meanings or your own "intuition." That doesn't work for the Thoth, it is shoving a square peg into a round hole. If you approach something completely alien to you with the approach that your "intuition" already knows everything, that's just not allowing new things to sink in. It isn't allowing it to teach you, and considering the readings you're getting, it smacks of hubris.
