The image shows us an ell, swimming through cool river waters. The sun appears to be just rising, giving us enough light to see by. The eel is an adept swimmer, able to cut through murky waters to get to where he needs to for safety, food or whatever his task may be.
The book indicates that the Eel brings wisdom and maturity to my tasks. Is the eel wise and mature? But I am with Mark on the “deep feelings being expressed at every turn“. Very much a case of that today!
