Joseph Campbell - The Ultimate Boon

...it is possible to observe, in the earliest phases of the development of the infant, symptoms of a dawning "mythology" of a state beyond the vicissitudes of time. These appear as reactions to, and spontaneous defenses against, the body-destruction fantasies that assail the child when it is deprived of the mother breast. 

"The infant reacts with a temper tantrum and the fantasy that goes with the temper tantrum is to tear everything out of the mother's body...The child then fears retaliation for these impulses, i.e., that everything will be scooped out of its own inside." 

Roehim

Anxieties for the integrity of its body, fantasies of restitution, a silent, deep requirement for indestructibility and protection against the "bad" forces from within and without, begin to direct the shaping psyche; and these remain as determining factors in the later neurotic, and even normal, life activities, spiritual efforts, religious beliefs, and ritual practices of the adult.

The profession of the medicine man, this nucleus of all primitive societies, "originates...on the basis of the infantile body-destruction fantasies, by means of a series of defense mechanisms."

Roheim

The first formula is abreaction in fantasy (my inside has already been destroyed) followed by reaction-formation (my inside is not something corruptible and full of faeces, but incorruptible, full of quartz crystals). The second is projection:' It is not I who am trying to penetrate into the body but foreign sorcerers who shoot disease-substance into people.' The third formula is restitution: ' I am not trying to destroy people's insides, I am healing them.'

Mt. Olympus - Ambrosia (not mortal)

Wotan - 32,000 heroes eat flesh of Sachrimnir, the Cosmic Boar and milk from she-goat Hidrum: she feeds on leaves of Yggdrasil, the World Ash. 

It is obvious that the infantile fantasies which we all cherish still in the unconscious play continually into myth, fairy tale, and the teachings of the church, as symbols of indestructible being. This is helpful, for the mind feels at home with the images, and seems to be remembering something already known. But the circumstance is obstructive too, for the feelings come to rest in the symbols and resist passionately every effort to go beyond. The prodigious gulf between those childishly blissful multitudes who fill the world with piety and the truly free breaks open at the line where the symbols give way and are transcended. The ineffable teaching of the beatitude beyond imagination comes to us clothed, necessarily, in figures reminiscent of the imagined beatitude of infancy; hence the deceptive childishness of the tales.
