A candle flame flickers. The room temperature drops by two degrees. You feel a presence at the edge of your awareness, and suddenly every instinct asks the same question: Who is this? That question is the beginning of discernment, and it is older than any grimoire. The practitioners of medieval necromancy called it discretio spirituum (the weighing of spirits). The Desert Fathers of the fourth century named it diakrisis (the sharp separation of one thing from another). Discernment of spirits for beginners is the practice of identifying, evaluating, and responding to spiritual presences based on observable signs, internal effects, and traditional tests. It is the tool that separates the practitioner from the passive medium, and it is the first skill a serious worker of the occult learns, often the hard way.
Where This Practice Comes From: A History of Testing the Invisible

The first written system for discerning spirits appeared in the early Christian monastic tradition. In the 340s CE, the Egyptian hermit Evagrius Ponticus wrote the Praktikos, a manual that taught monks to distinguish between the thoughts sent by God, those generated by their own passions, and those planted by demons. Evagrius called these last thoughts logismoi (a Greek word meaning reasonings or accusations). His student John Cassian brought the system to Western Europe around 420 CE, describing eight principal spirits that attacked the soul. Gregory the Great trimmed the list to seven in 590 CE, and the Western church had its seven deadly sins.
But the occult tradition runs a separate track. By the 1400s, European grimoires like the Munich Manual of Demonic Magic (anonymous, circa 1450) and the Key of Solomon (Latin manuscripts from the 1300s) gave detailed instructions for identifying spirits by their appearance, their name, and their response to command. A spirit that refused to state its name was suspect. A spirit that flinched when holy water was sprinkled (or, in goetic practice, when certain seals were shown) was classed as hostile.
The Renaissance magician Cornelius Agrippa wrote in his Three Books of Occult Philosophy (1533) that the discerning magician watches for three signals: the spirit’s attitude toward light, its effect on the room temperature, and whether it agrees to be bound by a circle. Agrippa was not inventing. He was compiling a folk knowledge that working magicians had carried orally for centuries.
Why These Tests Exist

That history explains why the tests we use today are not arbitrary. They come from direct, lived failure. People died, went mad, or lost their capacity for ordinary life because they trusted the wrong presence. The tests are not superstitions. They are scar tissue.
Discerning spirits begins with the body, not the mind. A presence announces itself through physical sensations before it ever speaks. The traditional list, compiled across multiple traditions, includes:
The room temperature drops or rises sharply, usually by more than three degrees. This is the most common sign and the least reliable. Drafts exist.
The air pressure changes. Your ears pop. The candle flame leans toward the presence, not away from it. This lean is considered a sign of curiosity or attention.
The hair on your arms and neck rises, but not from cold. Practitioners call this “the prickling” and treat it as the body’s natural warning system. Trust it.
A sound pattern emerges: three knocks at even intervals, a scraping that follows the walls, a whisper that has no source. Repetition matters. A single sound is random. A repeated pattern is communication.
A smell arrives without cause: flowers, rot, sulfur, ozone, or brimstone. The scent of sulfur, specifically, appears in the grimoire traditions as a marker for spirits of the infernal hierarchy.
You feel a weight on your chest or shoulders. In some traditions this is called “the hag” or “the press” (Old English ælf-siden, elf-sitting). It indicates a spirit that is trying to dominate rather than communicate.
One detail that rarely appears in beginner guides: the direction of arrival. In the works of the Elizabethan astrologer and occultist John Dee (1527-1608), his scryer Edward Kelley reported that spirits entered the circle from specific cardinal directions depending on their nature. Divine spirits came from the east. Neutral or natural spirits came from the south. Hostile spirits entered from the north. Dee’s records in his Spiritual Diaries (1581-1607) show him refusing to work with any spirit that entered from the north until he had confirmed its identity through multiple tests.
How to Test a Spirit’s Nature
The external signs are half the work. The other half is internal, and it requires the practitioner to develop a skill that cannot be taught in a book: the ability to distinguish your own thoughts from thoughts that arrive from outside.
The Desert Fathers called this “the discernment of thoughts.” The practitioner sits in silence and observes the internal landscape. A thought that arrives with calm clarity, leaves when dismissed, and does not loop back is likely your own. A thought that arrives with force, repeats itself, produces anxiety or excitement, and resists dismissal is likely external.
A spirit that is what it claims to be will feel like neutral information. It does not flatter you. It does not threaten you. It does not try to make you afraid for no reason. It does not demand worship, service, or fear.
A spirit that is deceptive will produce a rush of emotion. The emotions vary. Some practitioners report a sudden surge of love or protection that feels “too warm.” Others report a cold dread that does not match the situation. The golden rule across traditions: any spirit that demands immediate action without explanation should be treated as hostile until proven otherwise. This rule appears in the Theurgia-Goetia (a section of the Lemegeton, compiled circa 1681) where spirits are classified by their willingness to wait for the magician’s readiness.
The Light Test
Hold a candle or lamp between yourself and the spirit’s perceived location. A spirit that is transparent, casts no shadow, or appears to absorb light rather than reflect it is considered suspect. The medieval witch trials sometimes used this test to identify “familiar spirits” that were said to accompany witches. The logic is older: light is associated with the material world, and a spirit that cannot interact with light is either very weak or deliberately avoiding disclosure.
The Name Test
Ask the spirit its name three times. Do not demand it. A spirit that refuses all three times is either unable or unwilling to answer. In the goetic tradition of the Ars Goetia (the first section of the Lemegeton), the magician binds the spirit by its name. A spirit that will not give its name cannot be bound, and a spirit that cannot be bound is not safe to work with.
The test requires one judgment call: a spirit may give a name that is a title (“the Watcher”) or a description (“the one who stands at the threshold”). This is accepted in many traditions as long as the spirit provides a consistent answer each time. A spirit that gives a different name every time is lying.
The Seal Test
Show the spirit a symbol that corresponds to the tradition you are working within. For a practitioner of the Solomonic tradition, this might be the Seal of Solomon (the six-pointed star). For a folk practitioner, it might be a cross, a pentagram, or a specific sigil the spirit was summoned through.
A spirit that flinches, recoils, or becomes agitated at the sight of the seal is almost certainly hostile to that tradition. A spirit that bows, grows still, or acknowledges the seal is accepting the authority it represents. A spirit that shows no reaction is neutral and may not be bound by that seal’s power.
What the Tests Reveal and Their Limits
The tests do not “prove” the spirit’s identity in any scientific sense. They create a framework for making decisions under uncertainty. The practitioner who has run all three tests has more data than the practitioner who has run none. The practitioner who has run the tests and still feels uncertain has permission to stop the working and close the circle.
The tests also reveal the spirit’s relationship to authority. A spirit that refuses the name test but accepts the seal test is showing you that it respects hierarchy but does not trust individuals. A spirit that accepts the name test but flinches at the seal is showing you that it respects direct contact but does not recognize institutions. Both are usable relationships. Both require different handling.
Common Mistakes in Spirit Discernment
Treating every presence as meaningful. The vast majority of flickering candles, temperature drops, and creaking floorboards are physics, not spirits. Beginners chase shadows for months before they learn to let things pass.
Asking “are you friendly?” This is meaningless. A deceptive spirit will say yes. A neutral spirit will say yes because it does not care. A hostile spirit may say yes to get close. Ask what it wants, not what it is.
Assuming benevolence because the spirit says nice things. Flattery is the oldest tool in the spirit’s arsenal. The Goetia demons regularly address the magician as “master” and “lord.” They mean the opposite.
Working alone without records. The seventeenth-century occultist Robert Turner wrote in his Astrological Physick (1654) that the magician should keep a “Journal of Spirits” noting the date, the phase of the moon, the spirit’s name, the tests applied, and the outcome. Without records, you have no data. Without data, you cannot learn.
Staying past the point of discomfort. A spirit that makes you feel unsafe is not the spirit you should be testing. Close the working. Cleanse the space. Try another day.
FAQ
Can a spirit lie about its intentions? Yes. Deception is the primary risk in spirit work. The traditional tests are designed to expose dishonesty through repeated questioning and symbolic confrontation.
How long does it take to develop discernment? Most practitioners report 6 to 12 months of regular practice before they can reliably distinguish their own thoughts from external influence. Some never fully trust their discernment.
What if a spirit refuses all tests? Close the working immediately. A spirit that refuses to submit to testing is a spirit that will not be controlled. Do not negotiate. Do not argue. Close the circle and sanctify the space.
Is it dangerous to test an unknown spirit? The risk is proportional to the practitioner’s preparation. An unprepared practitioner who tests a hostile spirit may experience psychological disruption, physical sensations of dread or pressure, and recurring nightmares. This is why the safety protocols (circle casting, cleansing, protective sigils) exist.
The tests are simple. The practice is not. Discernment is a skill honed over years of quiet observation, failed attempts, and the slow accumulation of small signals that become a reliable language. It requires the courage to walk away from a spirit that refuses the test, and the humility to admit when you cannot tell the difference between a thought and a presence.
