Mother-symbols are characterized by an interesting ambivalence:
the mother sometimes appears as the image of nature, and vice-versa; but the
Terrible Mother is a figure signifying death (31). For this reason, Hermetic doctrine held that to ‘return to the mother’ was equivalent to dying. For the Egyptians, the vulture was a mother-symbol, probably because it devours corpses
(19); it also stood for the means whereby Hammamit (the universal soul) was
split up into separate parts to form individual souls (19). For the same reason, the
maternal sentiment has been said to be closely bound up with the nostalgic
longing of the spirit for things material (18), or with the subjection of the spirit to
the unformulated but implacable law of destiny. Jung mentions that in Jean
Thenaud’s Traité de la Cabale (of the 16th century) there is a mother-figure
actually represented in the form of a god of destiny (32). He mentions further that
the Terrible Mother is the counterpart of the Pietà, representing not only death
but also the cruel side of nature—its indifference towards human suffering (31).
Jung also notes that the mother is symbolic of the collective unconscious, of the
left and nocturnal side of existence—the source of the Water of Life. It is the
mother, he argues, who is the first to bear that image of the anima which the man
must project upon Woman passing from the mother to the sister and finally to the
beloved (32). A predominantly maternal social pattern—a matriarchal society—
is characterized, according to Bachofen, by special emphasis upon blood relationships, telluric allegiances, and the passive acceptance of natural phenomena.
Patriarchies are distinguished by a respect for man-made laws, the favouring of
works of art and craft, and obedience to the hierarchy (23). Even now that
matriarchal societies, sociologically speaking, no longer exist in the West, psychologically man is nevertheless passing through a phase when he is in all essentials dominated by the feminine principle. To come triumphantly through this
stage and to reinstate the masculine principle as the guiding-rule of life—bringing
to the fore the characteristically patriarchal qualities noted above—would signify
an achievement of the kind that was once symbolized by the transformation of
the ‘lunar work’ into the solar, or by the transmutation of mercury into sulphur.
To quote Evola: ‘Symbols of the earth-mother are: water, the mother of the waters, stone, the cave, the maternal home, night, the house of depth, and the
house of strength or of wisdom.’
