You know mine already, Liam.. like spokes in a wheel, indeed, it is the centre that matters, not which path you choose.
Have you thought that by taking Poseidon as your symbol of focus.. and that is all it is when you are aware that all the gods are one God.. the fish symbols tie in very closely with Jesus?
I personally believe you are right in thinking we can all attain that christ consciousness eventually, and that it is the goal our souls are aiming for. I also know that each of us may be right and wrong in our beliefs..but personally, I don't think it matters. I feel that if we see a goal and make that the object of our life's quest, living wholeheartedly what we believe and keeping our hearts and minds open to growth, I don't think we will go far wrong.
In CS Lewis's Narnia books, there is a young soldier who has, all his life, been a follower of Tash, who goes through the stable and emerges to find Aslan. When the young man questions this, Aslan tells him that although he had worshipped Tash, in truth his worship had been for Aslan. In other words, in the context of the book (The Last Battle) although the boy had named the object of his devotion Tash, and given it the face and symbolism of Tash, the inner truth behind the love in his heart had been for the force represented by Aslan.
This is worth thinking about.. no matter what face of divinity you hold in your mind, it is the truth of the force behind it that counts.
