The third book deals with the more advanced stages of yoga leading the seeker to the great reversal of the Trojan War that initiates the work in the depths of the vital and the body.

Several great heroic adventures mark the previous period:

- The war of the Lapiths against the Centaurs helps the seeker to track down in himself erroneous attitudes well hidden under deceptive appearances; for example, the deviance of the Ixion Lapith or "spiritual pride" that can still occur far on the path.

- The Boar hunt of Calydon attended by all the greatest heroes: Artemis sent a giant solitary boar, “wild and with white tusks” to ravage the orchard of Oineus every day. Meleager took command of a troop of heroes to hunt it down.


And for the first time in the myths, a woman was among the hunter-warriors, Atalante “equality”, seconding Meleager “the one who works for exactitude”. It is indeed in this work of “equality” or ”equanimity” that the seeker is now called for in order to achieve “detachment” represented by the sister of Meleager, Déjanire "the one who kills attachment”.

- The Wars of Thebes: the one of Seven against Thebes which saw the children of Œdipus killing each other and the one of Epigones which marks the completion of the work of purification.
Even before the start of these two wars, the seeker must be free from a terrible mistake: false wisdom. Indeed, when he arrived at the gates of the city, Œdipus had to defeat Phix or the Sphinge “the one that stops the penetration of consciousness into the being”, symbol of a simulacrum of wisdom. This Sphinge was the daughter that Orthros’ “falsehood” begat with his own mother Echidna “the stopping of evolution in the union”.

Here follows the study of several lineages including those of heroes involved in the Trojan War:

- The lineage of Tantalus which marks the evolution of "aspiration" and where Agamemnon and Menelaus, the leaders of the war, are present.

- The Trojan royal lineage of the descendants of the Pleiad Electra, symbol of the illumined mind.

- The Royal lineage of Sparta concerning “what is seeded” in which the stakes of war are contained, Helen “the truest evolutionary direction”.

- The lineage of the Asopos River with its illustrious descendant Achilles, “who endeavours to realise the two liberations, those of Spirit and Nature.” As king of the Myrmidons “the ants”, he takes care of the smallest movements of consciousness, the only branch of yoga that will lead to the final victory of the Achaeans.

 

Finally the author proposes a detailed interpretation of the two great myths of Greek Antiquity:

- The Iliad or the strike of Achilles, which explains that liberation in the spirit is not the ultimate realisation and that from now on, the seeker must not strive anymore for personal liberation, but for that of humanity as a whole, involving the most difficult of yogas, the one of the body.

- The Odyssey which describes the more advanced stages known at the time of the ancient Greeks, where it is found that spiritual endeavour develops according to a spiralled movement in which the seeker finds at deeper and deeper levels what he had already dealt with in the mind and vital. This explains the apparent similarity of many exploits of Jason and Ulysses.
Finally, the Odyssey, which is a myth relating “experiences”, is put in connection with its theoretical counterpart: the latest feats of Heracles, “praxeis” or “free actions” which complete the twelve labours or “athloi”, opening up the future.
