The term 'Mountain Lion' appears in the depth-psychology corpus primarily as an oblique or embedded reference rather than as a sustained symbolic object of study in its own right. The passages that approach it most directly do so through adjacent feline symbolism — lion, tiger, panther — and through the alchemical tradition's deployment of leonine imagery. The most concentrated locus is the alchemical literature, where Khunrath's phrase 'luring the lion out of Saturn's mountain cave' (cited by both Jung and von Franz) positions the mountain lion figure as a symbol of Mercurius emerging from the prima materia, the raw instinctual substance concealed within lead-like depression. Hillman's animal phenomenology in 'Animal Presences' and 'The Thought of the Heart' offers a counterpoint, treating the lion not through alchemical coding but through ecological and aesthetic presence — the lion's roar as the awakening force of the heart's responsive life. The Tarot commentators (Nichols, Place) treat the lion of the Strength card as the tamed instinctual nature, a field of psychological meaning that overlaps with, without naming, the mountain-dwelling great cat. Across these positions, the tension is consistent: between the lion as something to be integrated or drawn forth from depth (alchemical, Hillman) and the lion as something to be tamed or subdued (heroic myth, Tarot). The mountain setting consistently codes remoteness, sublimity, and the unconscious as a place of difficult retrieval.
One of the manifestations of Mercurius in the alchemical process of transformation is the lion, now green and now red. Khunrath calls this transformation 'luring the lion out of Saturn's mountain cave.'
Jung identifies the mountain cave as the alchemical locus from which Mercurius-as-lion must be drawn forth, linking leonine transformation to Saturn's dark, subterranean domain.

The lion's cubs are stillborn. They must be awakened into life by a roar. That is why the lion has such a roar: to awaken the young lions asleep, as they sleep in our hearts.
Hillman reads the lion not as something to be overcome but as the animating force of the heart, its roar the resuscitating power that restores responsiveness to an anesthetized psyche.

Lions are monocolored, a tawny yellow that symbolism ties to the sun, to gold, and to all the heroic virtues of undeceiving singlemindedness. Tigers are striped with contraries.
Hillman contrasts the solar, heroic symbolism of the lion with the chthonic, shamanistic register of the tiger, situating the lion within a masculine, unitary, heroic field.

The two lions are prefigurations of the royal pair, hence they wear crowns. Evidently at this stage there is still a good deal of bickering between them, and this is precisely what the fiery lion is intended to express — the passionate emotionality that precedes the recognition of unconscious contents.
Jung reads the lion's aggression as the alchemical expression of emotionality prior to the coniunctio, a psychic stage of unresolved opposition.

It is the battle between the developing ego and its instinctual roots, which must be tamed before the individual can become truly individual. But it is the particular sort of beast which is most relevant here, for this is a lion.
Greene frames the lion specifically as the instinctual adversary the heroic ego must confront and integrate as a precondition for genuine individuation.

Wild animals generally symbolize self-fulfillment because they are true to their instinctive nature, which is pure and uncorrupted by pretense, ambition, and other negative aspects of so-called civilized man.
Nichols treats the lion on the Strength card as an emblem of uncorrupted instinct, the religious and vital energy that civilized consciousness must learn to honor rather than repress.

How sudden emotions can literally seize us — how the animal side of our nature can spring upon us from behind to claim its own. At these times, ego consciousness is thrust aside.
Nichols uses the lion as a figure for autonomous affect complexes that overtake the ego, establishing the taming of the lion as a psychological task of conscious integration.

According to most alchemical texts, the green lion is the ore from which philosophical mercury is extracted and is also known as terra (earth), the unclean body, or Latona.
Abraham's alchemical lexicon defines the green lion as the prima materia in its rawest, most earthy state, the body of the Stone before purification — a foundational reference for understanding the mountain-cave symbolism.

Contact with wild nature, whether it be man, animal, jungle or swollen river, requires tact, foresight, and politeness. To drink the green lion's blood, then, would mean to assimilate.
Edinger glosses the green lion's blood as the alchemical substance of raw instinct that must be consciously assimilated rather than avoided or repressed.

The lion roar, the sound of the solar spirit, the principle of the pure light of the mind, unafraid of its own force, had broken forth in the night of stars.
Campbell associates the lion's roar with the heroic solar spirit, the awakening of conscious courage and spiritual illumination — a mythological register complementary to Hillman's psychological one.

I had a tendency to find a way to the conscious by going up, as I did on the mountain. The mountain was the kingdom of the sun.
Jung's personal account associates the mountain with solar consciousness and the kingdom of light, providing indirect mythological context for the mountain setting of leonine symbolism.

He turned himself into a lion and hurried to another part of the forest.
Von Franz notes a fairy-tale motif in which the lion form is adopted as a vehicle of power and swift action, reflecting the transformative potential of leonine identification in folkloric psychology.
