Several of his books were compilations of lectures he gave to this group; therefore, as the years went by, after his physical demise, there have been other attempts to get together for the same purpose as a result of this many new titles have emerged when addressing some of the topics he used to address before this audience.
At the time of his talks, the recordings of his discussions and lectures did not have a title; therefore we have used an empirical method to name them, this method is based on his habit of outlining the issues that he planned addressed before his talks, also trying to respect the name given to them when the recordings were labeled.
The physical space where these meetings took place was simple and austere. It was located in the center of Mexico City, the extraordinary feature of this place was his presence in these intimate settings that kept him immersed in the vortex of one of the largest capitals of Latin American, but it did not stop him from addressing the world and mankind in an original and challenging perspective.
Throughout the years, his great intellect, deep respect for what is sacred, and the weight of the mission he knew he was steward were deployed, giving it a stronger and stronger sense of urgency even to have eschatological implications.
He used to insist on sending a message to those who were interested in achieving self-fulfillment and taking part in the establishment of a new culture and civilization, assuming that the undertaking of the path of self-destruction given to mankind would end up affecting it. He did not see a way out of this self-destructive state in a social context but in a personal one this is why he urged everyone to test by oneself what he was teaching.
In short, what he teaches is based on the awakening of consciousness through the elimination of the psychological defects and the use of some specific techniques provided by him as well as the embodiment of the moral spiritual principles which everyone has as a potential development, this process is called "Second Birth " .
The Second Birth consists in the creation of inner bodies that make possible such extraordinary events it is based in the transmutation of the Sexual Energy. He dedicated most of his books, and many of his lectures, to explain procedures and symbols that are related to the "Sexual Alchemy” since it is because of it that we can achieve both the elimination of the ego and formation of the inner bodies. He strove to make clear that “the initiation” is the life itself and the progress in it is measured in relation to what is being achieved both in the awakening of consciousness as well as in the creation of the solar bodies.
