Deception occupies a wide and contentious territory in the depth-psychology corpus, appearing in registers that range from demonology and ascetic theology to psychoanalytic technique, Buddhist philosophy, and social critique. The Philokalia tradition treats deception as the primary weapon of demonic agency: the enemy works through subtle fantasy, illusory visions induced by arrogance, and the specious appearance of virtue to lead the soul away from God. John Cassian elaborates a parallel phenomenology, charting how demonic cunning twists scripture itself into seductive misdirection and how self-concealment aggravates spiritual pathology. Chögyam Trungpa recasts the problem in experiential terms: self-deception is not a moral failure but a structural feature of ego, the self-perpetuating dream by which the self secures its own continuity against the threat of openness. Pascal frames the epistemological version: reason and the senses engage in mutual deception, and the compulsion to hide one's faults from oneself constitutes a second-order evil beyond the faults themselves. Nietzsche adds a genealogical dimension, implicating cognition itself as a decorative lie that inflates the value of existence. Across these traditions a common tension persists: deception is simultaneously an external assault — demonic, institutional, interpersonal — and an interior condition that the subject perpetrates against itself, a distinction with decisive consequences for therapeutic, ascetic, and philosophical practice.
Ego is the fear of losing openness, the fear of losing the egoless state. This is the meaning of self-deception, in this case — ego crying that it has lost the egoless state, its dream of attainment.
Trungpa identifies self-deception not as a moral category but as the very structure of ego — the self-maintaining fiction that perpetuates itself through fear, hope, and the illusion of attainment.

This sort of attempt to prove our own uniqueness is just an attempt to validate our self-deception... We begin to realize that we have been deceiving ourselves and we begin to move closer to the genuine open way.
Trungpa traces the arc from self-deceptive inflation of spiritual experience through its inevitable collapse toward authentic openness, arguing that recognizing self-deception is itself the turning point.

It is no doubt an evil to be full of faults, but it is a still greater evil to be full of them and unwilling to recognize them, since this entails the further evil of deliberate self-delusion.
Pascal establishes a hierarchy of moral evil in which self-concealment and deliberate self-delusion are worse than the original fault, because they compound ignorance with the refusal of truth.

Not all cases of religious deception are deliberate. At times, religious subterfuge may be more a matter of self-deception than anything else. Unaware of their true motivation and equally unaware of how religion has been called on to conceal these motives, those who engage in religious deception may feel quite convinced of the rightness of their positions.
Pargament distinguishes deliberate fraud from unconscious religious self-deception, arguing that the latter — where the agent is genuinely unaware of concealed motivations — may be the more psychologically significant category.

This deception in its turn produces blasphemy as well as the fear induced by monstrous apparitions... arrogance is followed by delusion, delusion by blasphemy, blasphemy by fear, fear by terror, and terror by a derangement of the natural state of the mind.
The Philokalia maps a precise causal chain in which self-conceit produces illusory visions, which constitute a deception that cascades into blasphemy, terror, and mental derangement.

By means of what appears to be good he persuasively attaches its desire to what is evil, and by swearing falsely on the name of the Lord he leads the soul thus persuaded towards things other than those he has promised.
St. Maximos describes demonic deception as an ontological inversion: the devil appropriates the appearance of the good to redirect the soul's desire toward evil, making false appearance the instrument of spiritual destruction.

He tries to fool us by means of counterfeit pieces. He urges us on to some task which has not the authentic stamp of the ancients and which, seemingly for the sake of virtue, leads us into sin.
Cassian articulates the demonic strategy of using virtuous appearance as the vehicle for deception, so that piety itself — fasting, vigils, charitable visitation — becomes the trap.

The third kind of healing is a trick and deception worked by demons. A man caught up in obvious wrongdoing is an object of admiration because of the wonders worked by him.
Cassian identifies a third modality of healing — demonic counterfeit — in which spectacular works serve as instruments of deception designed to spread scandal and corrupt imitation.

The senses deceive reason through false appearances, and, just as they trick the soul, they are tricked by it in their turn: it takes its revenge. The senses are disturbed by passions, which produce false impressions. They both compete in lies and deception.
Pascal argues that the very faculties of knowledge — sense and reason — are structurally engaged in mutual deception, making the human subject constitutively incapable of transparent self-knowledge without grace.

Lying and deception go hand in hand with addiction because you are trying to hide your sin. You know that what you are doing is wrong so you hide it.
Shaw frames addictive deception as a consciously motivated concealment of acknowledged wrongdoing, distinguishing it from true self-deception while linking it to the structural dynamics of shame and denial.

The patient injures himself most, since he has to pay for every deception or subterfuge with an aggravation of his symptoms, or with fresh ones. Deception is so obviously disadvantageous to himself that he can scarcely avoid relinquishing such a course for good.
Jung observes that patient deception in analysis is self-defeating because the psyche's symptomatic response to concealment is more costly than disclosure, making honesty functionally compulsory.

In contrast to false teachers, who often create a condition of dependency in the student by claiming special access to truth, authentic teachers delight in sharing the source of their own realization with the student.
Welwood identifies the false teacher's deception as the claim of exclusive access to truth, which manufactures dependency rather than awakening, contrasting this with genuine transmission.

The fact that valid mythological motifs (for example, death and resurrection) have been used in this way for deception does not mean that in proper context they are still, necessarily, the 'opiate of the people.'
Campbell distinguishes the deliberate deployment of authentic mythological motifs for social manipulation from their genuine ritual function, warning against conflating deceptive use with inherent falsity.

The arrogance inherent in cognition and feeling casts a blinding fog over the eyes and senses of human beings, and because it contains within itself the most flattering evaluation of cognition it deceives them about the value of existence.
Nietzsche frames cognition's inflation of its own worth as a constitutive self-deception — a survival-serving lie that makes existence tolerable by misrepresenting its actual value.

He frequently entertained a demon as if he were an angel and received revelations from him, often seeing what looked like the light of a lamp in his cell. Later, he was ordered by this demon to offer his son as a sacrifice to God.
The Philokalia presents a case study in demonic deception by angelic simulacrum, illustrating how lack of discernment renders the ascetic vulnerable to the most extreme moral catastrophe.

We benefit in particular from removing every sense of beauty from the thought of redemption, and even need to do so, or else we will deceive ourselves again because we like the word and because a beautiful shimmer spreads out over the thing through the great word.
Jung warns that aesthetic and linguistic appeal to luminous concepts like 'redemption' is itself a vector of self-deception, arguing that stripping away beauty is a condition of honest encounter with the work.

To come back to your question as to whether it is possible for patients to trick the analyst by making deceptive use — perhaps involuntarily — of his mode of expression, this is indeed a very serious problem.
Jung flags the technical problem of patients unconsciously adopting the analyst's conceptual vocabulary as a means of deception, blurring the line between deliberate and structural self-concealment.

Everywhere the ass looks out from under the lion's skin. He plays his part execrably by exaggerating it beyond all reason; and he loses control over himself as soon as his senses are aroused.
Auerbach's reading of Tartuffe illustrates the structural instability of performed deception: the deceiver's authentic nature continually erupts through the pretense, making sustained dissimulation psychologically impossible.

Autobiography itself, is essentially duplicitous because the auto and the bio may represent two distinct tales, that of the acorn and that of the life.
Hillman treats autobiographical narrative as inherently duplicitous — not through moral failure but through the structural divergence between the daimon's story and the biographical record.

You must never relax your attentiveness of heart, your watchfulness, your power of rebuttal or your prayer to Jesus Christ our God... for He alone, as God, knows the deceitful ways of the demons, their subtlety and their guile.
The Philokalia positions ceaseless watchfulness as the necessary response to demonic deceit, grounding anti-deceptive practice in the superior knowledge of Christ rather than in unaided human discernment.
