A PRACTICAL MANUAL FOR PROFESSIONALS, UNDERSTANDABLE BY BEGINNERS
[ INTRODUCTION
This work is published to offer the general public some knowledge of which they are either thoroughly ignorant or, more commonly, they misunderstand, but also to make the work of Psychics and Mystics easier.
Occultism is a positive science because it is based on experiments. The Alchemists of the Middle Ages, many of whom paid with their lives for their investigation or were considered sorcerers or madmen, sought to achieve the transmutation of matter, laying the foundations for today's science that can do it, and no one disputes it.
Occult sciences explore the vast field of both the visible and invisible world, which are rich in mysteries, and work to discover the link between them; with each discovery, they restore the reference points as connecting links so that the occultist can intervene between cause and effect.
Therefore, occultism is not the denial of science but science in its most comprehensive form, which includes within its limits the absolute and the infinite.
Occultism teaches the inseparable interdependence between phenomena and events, cause and effect. But the occultist has the freedom to choose the path they will follow. Predestination is presented as a general framework in which we move. There are always development opportunities, and we can help events unfold according to our wishes.
The three keys with which the coherence of cause and effect is deciphered are the following: Synchronicity, Correspondence, and Coordination. The place and date of a human's birth define their identity more than their form or name. The where and when -an idea is born or a task is started- shapes its dynamics.
Birth occurs at such a place and time as to allow the fulfillment of its destiny. Life is not ruled by the stars because of the space-time of its birth. The birth itself agrees with the planetary indications and gives the necessary conditions for this evolution of life ...]

[SYMBOLS ON THE ALTAR
About the Triad.
Three is the first non-composite number and, according to Iamblichus, the leader of the return of the past. The Triad is not the sum of one and two (therefore non-composite).
While the Dyad contains the first two manifested elements in Nature (Motion and Life), the Triad is the manifestation of the Monad in Creation.
Theon observes that the Triad with the Monad and the Dyad creates by composition the number six, which is the first perfect number, and Aristotle calls three a law based on which everything is ordered. With the Triad, the World exists, argues Hermes Trismegistus.
The connecting role of the Triad in creation was also formulated by Plato, who said that it is impossible to connect the two without the existence of a third; therefore, the Universe owes its existence to the Triad.

About the Tetrad.
The Pythagoreans called the first Tetrad of numbers "Tetraktys" because they were created by the composition of the Ten, which numerologically returns to the source, the Monad, from which everything begins.
The Tetrad is considered to include all the development of spirit manifestation down to the physical realm and return to cause.
Tetraktys is the source of eternal nature, as included in the Pythagorean oath. Iamblichus describes the existence within nature as a result of the Tetrad, saying that it is the creator and cause of all things.
Triangular numbers, with the formula [N (N]1)] /2, are derived from Tetraktys.
Hierocles mentions that the first solid shape (pyramid) is in the Tetrad because the point corresponds to the Unit, the straight line to the Dyad, the surface (triangle) to the Triad, and the solid corresponds to the Tetrad. By the Tetrad the tetrahedron is formed, of which the Triad produces the base, the Dyad the edge, and the Monad the vertex.
The Tetrad is the result of the creative act of the Triad. This dynamic manifestation ...]
