Corresponding to the brain is the lion, which descends to eat the sacrifice, and upon it is stated: (Ez. 1:10)... and the face of a lion, to the right of the four of them... The heart is to the left, and upon it is stated: (ibid.) and the face of an ox, to the left of the four of them. The lung is the eagle, which has wings with which it flies, and upon it is stated: (ibid.)... and the face of an eagle to the four of them.
‘Thought’, which is ‘the human’, rides above all of them, and they are his chariot – like horses for people. The forces of the brain, are the ‘bones’ in the sacrificial-offering: (Ez. 37:7)... and the bones came together, bone to its bone. The forces of the lung and the heart, are the ‘veins’, their connection and joining and movement, is the wind∞ruḥa of the wings of the lung, and it is: (Gen. 1:2)... the spirit∞ru-aḥ of ELQYM, was hovering, upon the face of the water [Var. which is the brain] because the lung [Var. the head] is comprised of both-of-them, like a bird composed of water and land, and they are comprised of both-of-them.
