Occlumency

**Occlumency** was the magic of closing one's mind against Legilimency. It was ancient, and had existed since ***medieval times***. It could prevent a Legilimens from accessing one's thoughts and feelings, or influencing them. A wizard or witch who practised this art was known as an **Occlumens**.

## Methods

> I told you to empty yourself of emotion! ... Fools who wear their hearts proudly on their sleeves, who cannot control their emotions, who wallow in sad memories and allow themselves to be provoked this easily — weak people, in other words — they stand no chance against his powers! He will penetrate your mind with absurd ease, Potter!

 File:Occlumency lessons OOTPF.jpg
The most basic form of Occlumency, judging from Severus Snape's early ***lessons*** on the subject to Harry Potter, involved clearing one's mind — making it "blank and empty" — in order to prevent a Legilimens from perceiving one's emotions and thoughts. More advanced Occlumency involved suppressing only the thoughts, emotions, and memories that would contradict whatever it was an Occlumens wished a Legilimens to believe.

This produced a "faux" layer of mentality that could totally throw off the perspective of one who used Legilimency into thinking that the said layer being the legitimate one whilst its bona fide counterpart lay deeper within. Hence, it was not obvious that Occlumency was being used even if the person was lying. It required a great deal of willpower, as with resisting the ***Imperius Curse***, as well as a high degree of mental and emotional discipline. It was also one method of resisting the influence of ***Veritaserum***.

Considered to be an obscure branch of magic despite its usefulness, Occlumency was not part of the normal curriculum taught at Hogwarts School of Witchcraft and Wizardry and appeared to be a rare and difficult skill.

## Examples

> I am about to attempt to break into your mind. We are going to see how well you resist. I have been told that you have already shown aptitude at resisting the Imperius Curse.... You will find that similar powers are needed for this.... Brace yourself, now.... Legilimens!

> Snape teaching Harry Potter Occlumency, Harry Potter and the Order of the Phoenix

***Bartemius Crouch Junior*** was an accomplished Occlumens, as he managed to hide his true mind from Albus Dumbledore and Severus Snape, both accomplished Legilimens, while disguised as ***Alastor Moody***. Had Barty not been groggy when stunned later that year, he would have had the prowess in Occlumency to resist the Veritaserum.

In the ***1995–1996 school year***, Albus Dumbledore had Severus Snape teach Harry Potter Occlumency in an effort to prevent his mind from being penetrated and influenced by Lord Voldemort. Snape was a highly skilled Occlumens, being able to successfully deceive extremely accomplished Legilimens Voldemort, but his lessons with Harry were ultimately unsuccessful. Harry was not able to repel most attacks, though it is likely that the personal enmity between him and Snape as well as the stressful events in his life that year hindered his ability; while Snape was not teaching in an encouraging way, Harry's climbing interests in Voldemort's repeated attempts at the Hall of Prophecy made him further neglect his practice of the skill. He eventually gave up attempting to learn. Harry later managed to block his connection to Voldemort, on occasion, by focusing on feelings of love and grief, rather than by using Occlumency.

Snape himself also employed Occlumency to hide his loyalty to the Order of the Phoenix from Voldemort, and due to his well-known mastery, both sides had difficulty trusting him.

Albus Dumbledore was also an exceptional Occlumens, having been one of the few to be capable of repelling Voldemort's Legilimency and he also expressed confidence in his ability to teach Harry the art but chose not to due to fearing Voldemort's reaction to how close they were.

After the Battle of the Department of Mysteries, Voldemort realised the dangers of his connection with Harry, and employed Occlumency to seal off the link, thus freeing Harry from feeling any pain from his lightning-bolt scar and also dreams of what Voldemort was doing. However, by ***1997*** to ***1998***, Voldemort started losing control due to repeated failures of his Death Eaters infuriating him more and more, and the reported losses of his Horcruxes became a tipping point where he forgot to close his mind, allowing the thoughts to be seen by Harry as he mentally organised his Horcrux hiding locations.

In 1996, Bellatrix Lestrange trained her nephew, Draco Malfoy in Occlumency so that he could keep his mission to kill Albus Dumbledore a secret. Draco became skilled enough to repel Snape's attempts at Legilimency. Draco's success was due to him shutting out his compassion to become the bully he is, making it easy for him to close his mind. Despite this, Dumbledore did not confront Draco earlier regarding the assassination attempts due to fearing Voldemort would use Legilimency on Draco to discover it, suggesting that Voldemort's Legilimency is able to overpower Draco's Occlumency.

## Etymology

The word "occlumency" comes from the Latin *occludere*, meaning "to shut up" and *mens*, for "mind".

In Czech, Occlumency is named "Nitroobrana". It comes from Czech "*nitro*" meaning heart and soul inside human and "*obrana*" which means defence.Template:Fact

## Behind the scenes

* On the subject of Occlumency, J. K. Rowling has discussed why Draco Malfoy would be skilled at it while Harry Potter was not:
	+ *"...I think Draco would be very gifted in Occlumency, unlike Harry. Harry’s problem with it was always that his emotions were too near the surface and that he is in some ways too damaged. But he's also very in touch with his feelings about what's happened to him. He's not repressed, he's quite honest about facing them, and he couldn't suppress them, he couldn't suppress these memories. But I thought of Draco as someone who is very capable of compartmentalising his life and his emotions, and always has done. So he's shut down his pity, enabling him to bully effectively. He's shut down compassion — how else would you become a **Death Eater**? So he suppresses virtually all of the good side of himself."*
* Occlumency, being a "magical defence of the mind against external penetration" most likely will make the use of the Imperius Curse against an Occlumens either ineffective or at the very least reduce its effectiveness, although this is unconfirmed. Snape did regard the power required to utilise Occlumency effectively as similar to that of resisting the Imperius Curse.
* Occlumency does not appear to be a generally offered subject of study at Hogwarts and is probably only taught in private courses to students who show potential for it. Snape described it as an "obscure branch of magic", further suggesting that it is lesser known to the community as a whole.
* Narcissa Malfoy may have been an Occlumens, as she lied to Voldemort about Harry's demise without consequences. However, Voldemort may not have been using Legilimency on her at the time, as he might not have believed she would lie to him with her family's lives at stake, a sign of Voldemort's greatest weakness: arrogance.
* Lucius Malfoy may have been attempting to use Occlumency against Albus Dumbledore. When questioned about his role in the second opening of the Chamber of Secrets, Lucius was described as having a blank look on his face while maintaining eye contact with Dumbledore. It's unknown if he was successful, though Dumbledore probably knew the truth regardless.
* According to ***W.O.M.B.A.T.***, it is possible that Occlumency can guard against possession.
* Voldemort employed Occlumency against Harry Potter to try to end the connection but started to lose control during the events of 1997 and 1998.
* Harry Potter briefly used Occlumency against Voldemort, although he has never been able to master it. Also of note, while Harry's use of Occlumency in the books was negligible, he was nigh-effortlessly able to throw-off the Imperius Curse (both by Bartemius Crouch Junior-as-Alastor Moody, and by Tom Riddle), by willpower-alone.
* Remus Lupin was able to conceal the fact that Sirius Black was an unregistered Animagus from Albus Dumbledore and Severus Snape, both highly skilled Legilimens, throughout his entire tenure teaching at Hogwarts in spite of the latter's intense dislike for him and stated suspicion that he was aiding Sirius Black. Dumbledore only found out because Lupin told him voluntarily, and because Black revealed himself in front of Ron Weasley. It is unknown if he was using Occlumency to conceal this knowledge or if Snape and Dumbledore just never used Legilimency against him.
* The Wizengamot believed that Sirius Black might have been an Occlumens, as they believed that even if they give him a fair trial under the influence of Veritaserum, he would still be able to resist it with Occlumency or other tricks.
* As Dumbledore was not suspicious when Barty Crouch Jnr used Occlumency when disguised as Alastor Moody, it's possible that the real Moody was skilled in this field as well. Given Moody's skill as an auror and paranoia, he likely was a skilled occlumens.
* Vinda Rosier may have been an Occlumens, as Queenie Goldstein could not tell if Vinda was lying to her. This would make sense, as Vinda was Grindelwald's lieutenant, and Bellatrix Lestrange, who was Voldemort's lieutenant, was also an Occlumens.
