Arcana Coelestia # 6292
6292. 'Place your right hand on his head' means that good should accordingly occupy the first place. This is clear from the meaning of 'placing the right hand on a head' as considering to occupy the first place, as above in 6269, 6287. The placing of his hand by one on the head of another when he was going to bless belonged to a custom received from the ancients. For the head is where a person's actual powers of understanding and will reside, whereas the body is where actions in response and in obedience to them are located. Thus 'placing a hand on the head' was a representative act, denoting that a blessing should be imparted to a person's understanding and will, thus to his real self. That same custom originating in those ancient times remains even to this day and is followed at ordinations as well as in blessings.

6287. 'And Joseph saw that his father placed his right hand on Ephraim's head' means a discernment that he considered truth to occupy the first place. This is clear from the meaning of 'seeing' as understanding and discerning, dealt with in 2150, 2807, 3764, 4567, 4723, 5400; from the representation of 'Joseph' as the internal celestial, dealt with in 5869, 5877, 6224; from the representation of Israel, to whom 'father' refers here, as spiritual good from the natural; from the meaning of 'placing the right hand on the head' as considering to occupy the first place, dealt with above in 6269; and from the representation of 'Ephraim' as truth present in the understanding part within the natural, dealt with above in 6234, 6238, 6267. From all this it is evident that 'Joseph saw that his father placed his right hand on Ephraim's head' means a discernment by the internal celestial that spiritual good from the natural considered truth to occupy the first place. See what has been stated and shown above on these matters in 6256, 6269, 6272, 6273.
