[5] Napoléon switched careers into teaching Germanic languages to Belgian children, both black and white, and the family moved to Luluabourg.

In 1966, he enrolled in the prestigious Université libre de Bruxelles with a scholarship; his brother, also a student there, described him as a "serious idealist" at the time, not interested in money.

[7] At home however he was disciplinarian and occasionally physically abusive; a teacher of Jouret's sister recalled she sometimes arrived at school sobbing and confessed to her that their father made their family life difficult.

As a result of this he spent 14 months mostly immobilized in bed and subject to constant medical care, an event which he described as making him lose his faith in modern medicine.

[2] In 1977, both Jouret and his female companion[14] Marie-Christine Pertué, a sophrologist four years his junior,[15][16] became affiliated with the World Teacher Trust (WTT).

[21] In a letter in 1983, Jouret told their friends he and Pertué had mutually decided on a divorce, while in actuality Di Mambro had ordered they separate, portraying the couple as having a "cosmic incompatibility".

In a ceremony, Pertué was "emptied" of her "spiritual content", and condemned to wander until the day she died; Jouret was advised not to contact her, however they did interact occasionally in the following years.

[27] Within the year Origas's daughter forced him out of the group over a dispute involving leadership and funds, resulting in a schism with half of ORT going with Jouret.

His specific presentations included ones titled: "Old Age: The Doorway to Eternal Youth", "Love and Biology", and "Christ, the Sphinx, and the New Man".

Jouret was known as an excellent speaker, and according to former member Hermann Delorme:[29] You start listening and by God, you know, you just all of a sudden feel so attracted to what he is saying.

[44] Jouret was noted to act "haughty, distant, or frankly contemptuous" to black members of the Solar Temple in Martinique, while accepting the whites.

[45] The members were terrified, but Jouret gave them a solution, which was to move to the group's Canadian base, which he said would be protected due to it sitting upon a large granite plate with a strong magnetic field.

[48] Jouret advised them to not pay taxes and borrow huge amounts of money, used to fund the new location in Quebec, as after they died it would not matter.

[48] Following the 1988 Saguenay earthquake, the view held by Jouret and other Templars that Quebec would be a safe haven from the impending apocalypse was damaged, which was the main reason they had moved to Canada.

[49] The members of the Sacred Heart commune disliked Jouret, accusing him of a lack of financial transparency and sexual exploitation of women.

[50] Canadian members began to question him, and Jouret was replaced as the Grand Master of the Sacred Heart commune by Robert Falardeau in about 1990.

[52] Jouret founded a separate group, l’Académie de Recherche et Connaissance des Hautes Sciences or ARCHS (a pun on the "ark of survival"), taking several loyal members with him.

[53] Jouret, having given up his profession as a homeopath to devote himself fully to the OTS, began lecturing on personal development at various companies, universities and banks, mainly in Quebec.

[55] Members in Martinique were beginning to be frustrated with Jouret, viewing him as a dictator who was controlling and intruded unnecessarily into their private lives.

"[56] In March 1993, two members of the OTS – Jean Pierre Vinet and Hermann Delorme – were arrested for attempting to purchase three semiautomatic guns with silencers, which are illegal in Canada; this came after Jouret had encouraged them to buy the weapons.

[...] What a planet, my God, what the hell did we do to land on this shit.Vinet and Delorme appeared in court on the charge of trafficking prohibited weapons on 30 June 1993.

He plead guilty, but obtained conditional discharge at his request, which kept his criminal record clean and allowed him to keep practicing medicine.

[61] The judge believed that the weapons purchases had been made in a "defensive context", and that the individuals involved had already been punished by the media coverage.

[62] Jouret and the other two men were given only a light and symbolic sentence after the crime: one year of unsupervised probation and a $1000 fine intended to be paid to the Red Cross.

[61] In the aftermath the media took interest in the group; the Canadian press began to report, using information gained from police wiretaps, conversations between members of the OTS, which they described as a "doomsday cult".

[64][63] Following the gun scandal, Jouret became very paranoid and concerned with purported injustice, as well as the legal investigation he faced in several countries.

[71] They declared that, upon death, they would acquire "solar bodies" on the star Sirius (though members also gave Jupiter or Venus as an alternative destination).

[72][32] The letters maintain a persecuted rhetoric,[73] largely devoted to complaining about the treatment faced by Vinet and Jouret in Canada.

[79][80] Following the deaths in Cheiry, Jouret was recorded as calling Di Mambro, possibly to inform him that it had been a success, and shortly after so did Egger.

A note was found in Di Mambro's chalet, which read:[15] Following the tragic Cheiry Transit, we wish to make it clear, on behalf of the Rosy Cross, that we deplore and totally disassociate ourselves from the barbaric, incompetent and aberrant behavior of Doctor Luc Jouret.
