Jung referred to this transpersonal memory as the collective unconscious. Here Jung is quoted in Wikipedia: “My thesis then, is as follows: in addition to our immediate consciousness . . . there exists a second psychic system of a collective, universal, and impersonal nature which is identical in all individuals. This collective unconscious does not develop individually but is inherited. It consists of pre-existent forms, the archetypes, which can only become conscious secondarily and which give definite form to certain psychic contents.” [C. G. Jung, The Archetypes and the Collective Unconscious (London 1996) p. 43
Again from Wikipedia: "Jung also made reference to contents of this category of the unconscious psyche as being similar to Levy-Bruhl's use of collective representations or "représentations collectives," Mythological "motifs," Hubert and Mauss's "categories of the imagination," and Adolf Bastian's "primordial thoughts."
The Simple Explanation refers to these collective memories as culturally shared "memes" and "meme chords." A person can be defined by the memes they cling to. To a large extent, one's memes shape one's personality.
Biologist Rupert Sheldrake has written extensively about, and staked his professional reputation upon, a scientifically controversial process called "morphogenetic fields." How does an oak tree develop from an acorn? By information carried in the morphogenetic field surrounding the acorn. Sheldrake explains that morphogenetic fields are to life forms what quantum probability clouds are to sub-atomic particles, carrying the information that gives rise to particular biological manifestations of form.
The Simple Explanation would site these morphogenetic fields at the zero-point field at the center of the toroid, part of the metaversal information streaming into our universe through our universal unit of consciousness, tempered by the organism's karmic record and acquired memes. In the case of the acorn and the oak tree, the morphogenetic field of the oak tree provides the genetic blueprint, while the mama tree's karma and memes provide the individualized epigenetic pattern that tells which genes to turn on and off. What karma can a tree have? Its karma is the record of its life--nutrients, history of water availability, pest attacks, and so on. What memes can a tree hold? "The sun feels good on my leaves; must follow the sun."
