Yeah I guess its the sun and moon.
I see Tahuti in his splendour at the prow as a guiding force, an observent yet intuitive force. An adventurous, lets go this way force. (on the Nile they had -and still do in parts, a look out on the prow to help navigate through sandbanks, rocks, hippos, etc), its also an intuitive thing as well. He helps to move the boat by communicating clearly with the helmsman, Ra Hoor, powerfull force and vigourous, paddling and steering from the helm.
I see the same forces at work in the Lust card, with Babalon as Tahuti, Beast as Ra Hoor and I use it all as an analogy for the workings of my concious / unconcious, male female side ( internally and externally in relationships). And hopefully in society as well. And also in the analogy of how I rule my 'Empire'
The lesson here for me is that we have a stong dominating vigorous force and a more subtle intuitive intellegent force and although both should be in balance the inherent nature of them can tend to lead to imbalance so we should be aware of keeping them in balance.
There is much more in it all of course but I'm just connecting it to the thread.
